bgmCoder's questions

We use Windows 10 with IIS10 for developing my webapps in Visual Studio 2019.

Now I've published my working dev site to the production server running IIS 6.2 on Windows Server 2012. However, when started, the site isn't available, not even if I start it from IIS using it's local address.

The site is running and the application pool is started for this site and the bindings are correct.

Even if I add a simple test.html page with nothing special, I can't load that page.

I've upgraded .net on the server to 4.8, and the site targets 4.7.2.

What am I missing?

We are using a DHCP server out of a linux OS right now for our subnet. I am thinking of changing to a Windows DHCP Server, however, because it might be easier for future admins.

What I want to do is to add the DHCP Server role to Windows Server (which I know how to do) and set up the DHCP options. I need to be able to configure in the options what I have in the linux DHCP options (tftp-server-name; netbios-name-servers, ntp-servers).

My question however, is this: can I set up this DHCP server and test it on just one or two devices without interfering with the DHCP server (on the linux box) that manages my network? Can I add the role to Windows Server without that taking over DHCP duties on my network until I get it configured?

Our server is a Dell Poweredge R610. There is no iDRAC installed, but I understand it still has iDRAC6 Express by default.

When I boot the server, it says System Services Disabled and it won't let me boot into BIOS or OS. So I let the boot procedure go on until the end where it says:

Initializing IDRAC....

I have to wait for this to time out - about two or three minutes. Then I get this message:

Alert! IDRAC6 communication failure.  Rebooting.

On the second boot, it is all the same as above, except that at the end it says:

Alert! iDRAC6 not responding. Power required may exceed PSU wattage

At this point it lets me push F1 to continue to OS or F2 to enter BIOS. Both of these options work.

My problem is that there is no ctrl+e option to enter iDRAC settings.

I have tried resetting the nvram on the motherboard by moving the jumper, and I've tried removing complete power (even flea power), but it doesn't make any difference.

How do I fix this? I can't boot the machine without a long delay and user intervention. This is similar to this thread, but I'm not trying to login to the iDRAC at all (and yes, I am familiar with the troubleshooting guide).

[bump]

Oh, I guess nobody knows of a fix besides replacing the motherboard? Maybe there is just a component to replace? I'm dying here.

[update]

Apparently, whatever is wrong also disables the Virtualization settings in the BIOS, too, making it impossible to start any virtual machines hosted by Exsi.

Using Powershell, how can I get the UserID of an account if I don't know which domain it is in?

For example, I have a Mail-User account called b.newhart and I can fetch information using that as the -identity with the get-recipient command.

But I need to know the UserID which has the domain name attached to it - for example, [email protected]. This is the UserID that you can see in the Admin panel of Exchange Online.

The reason I need the UserID is so I can use Set-MsolUserPassword on that account. To use this command, I need to specify the -UserPrincipalName which is the UserID. For full o365 accounts (with mail) I can use just the identity, but for Mail-User accounts I need the UserID with the domain name too, not just the identity.

We have very many mail-users from various domains, and the usernames are all standardized first initial + last name. So if I can reset their passwords by just knowing their identity then it would be wonderful.

So, How can I get the the UserID of a Mail-User account? OR how can I reset the password for a Mail-User account without knowing the domain designation?

In my Office365 online setup I have an Office365 Group (unified group) and I want to change it to a Mail-Enabled-Security-Group.

I've searched the world over but cannot find a way to do this via powershell. Is there a command for this?

If you are interested in my reason for doing this, look at my other question.

In my Office365 I have an Office365 Group. Whenever I add a Mail-User (external) to the group they receive the welcome message from the group, but it is in plaintext, complete with image file attachments and winmail.dat.

The message comes across like this:

Welcome to the Roadkill Cafe group.

[cid:office365_icon_orange]

[cid:group_photo.jpg] Roadkill Cafe Welcome to the Roadkill Cafe group.

Roadkill Cafe group

[cid:welcome_onenote_icon]https://outlook.office365.com/owa/[email protected]/groupsubscription.ashx?realm=roadkillcafe.com&source=WelcomeEmail&action=onenote Share noteshttps://outlook.office365.com/owa/[email protected]/groupsubscription.ashx?realm=roadkillcafe.com&source=WelcomeEmail&action=onenote

Capture ideas and images in OneNote.

[cid:document_icon]https://outlook.office365.com/owa/[email protected]/groupsubscription.ashx?realm=roadkillcafe.com&source=WelcomeEmail&action=files View and share fileshttps://outlook.office365.com/owa/[email protected]/groupsubscription.ashx?realm=roadkillcafe.com&source=WelcomeEmail&action=files

View, share, and collaborate on content using SharePoint.

I have tested this with my local email server and with Yahoo.

However, if I add one of the non-external users (licensed o365 user), the message is sent in html. Or, if in OWA, if I add a "guest" to the group who has a yahoo.com address, that person is also sent a normal html email like it should. I have also tested this with a gmail account.

So I added a remote domain under Exchange > mail flow > remote domains and configured that domain for Always use rich-text format (it was default set to follow user settings) and I changed the character sets to Western European. But this had no effect.

This MS help document says to make an adjustment that will force the message into plaintext and eliminate the winmamil.dat file altogether. However, I want the message to be in html, not plaintext. And besides that, none the three settings (Use rich-text format: Always, Never, Follow user settings) have any effect on the message at all.

How can I fix this?

[update]

Apparently, the mail-user receives ALL email correspondence in plaintext, not just the welcome message. This happens when you post anything in "conversation" in the group itself.

However, if I send an email to that same group, it is received as html! Go figure that. Post to the group directly and it sends plaintext; send an email to it and it sends html.

[update]

So I tried using powershell against the mail-user object like this, but this also did not change the welcome message to html:

set-mailuser -identity [email protected] -messageformat mime -messagebodyformat html

We just installed mrtg on our Windows Server 2012 and I am having trouble getting it to run as a service. I'm following the guide here, but am still stuck.

First, if I run mrtg manually, whilst specifying a config file, it does work and does generate graphs.

But for the service, I placed the files srvany.exe and instsrv.exe in c:\mrtg\bin (I removed the version number from the directory name, so it's all located now at c:\mrtg).

instsrv MRTG c:\mrtg\bin\srvany.exe

And I merged the regedit file into the registry and I can see the keys are there if I go and look. You can see from the path to Perl that I've installed the 64 bit version of Perl.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MRTG-PA500\Parameters]
 "Application"="c:\\perl64\\bin\\wperl.exe"
 "AppParameters"="c:\\mrtg\\bin\\mrtg --logging=eventlog c:\\mrtg\\bin\\mrtg-MyDevice.cfg"
 "AppDirectory"="c:\\mrtg\\bin\\"

Now, after I do all of this, the service is indeed, created, but when I try to start it, it starts and stops.

So I created a domain account for the service and assigned it to the service and gave read/write/modify rights to the mrtg directory and it's web directory, but it still won't start.

What am I missing?

[update]

Also, if I use the commandline equivalent to what is set in the reg entry, then I get some weirdness.

c:\mrtg\bin>perl mrtg --logging=eventlog mrtg-mydevice.cfg
Use of uninitialized value in subroutine entry at C:/Perl64/lib/Win32/EventLog.pm line 73.

[update]

I just found this, which states that svrany.exe is not really fit for Windows 7 (or Server 2012 after that). I know some of the links on the mrtg site are pretty old. Maybe I just can't use srvany?

But I think I probably have some configuration issue.

We recently upgraded our single-domain Windows network by adding two new servers. We promoted them both to domain controllers and removed the domain controller from our webserver (which was set up back when we had only one server). This server (windows 2008 R2) ran IIS 7.5 and hosted Sharepoint and Asp.net pages.

The new domain controllers are both GC and work perfectly.

Now, when we removed the Domain Controller role, the permissions got screwed up (Microsoft knows this happens). So now I want to fix it.

Before, my websites and sharepoint were all configured using domain accounts. Every site in IIS stopped working until I (by way of a test) added the application pool accounts to the local administrators group in which case they started working.

I've already made sure the account has read/write/execute rights for the site's virtual directory.

Is there a standard procedure for recovering from this? How do I get my asp.net site (much less sharepoint) back online without making the app-pool account a local administrator?

[edit]

Okay, so for a simple asp.net site, what do I need to do to get it running? So I tried creating a local user account for it's application pool, and gave it rights on the site's directory, and set the password in IIS. Still, I get "service unavailable" when I browse to the site. And the application pool always stops when I hit the page.

We have our own domain and have several subdomains. One of the sites needs to be accessed only via SSL, but people are allowed to type http and still arrive there. The URL-Rewrite forces the http into https.

So my two subdomains are: sub1.domain.org and sub2.domain.org.

Thus, if I type

http://sub1.domain.org/page_on_domain1

it is rewritten to

https://sub1.domain.org/page_on_domain1

-which is correct. But if I do this (which is not possible - page_on_domain1 does not exist on sub2.domain.org:

https://sub2.domain.org/page_on_domain1

My url-rewrite rule seems to work properly, but I want that last address to give me an error page instead, since the page doesn't exist on that subdomain.

I am testing this in Firefox on Windows 7 x64 Pro.

My url-rewrite rule is as follows (I am doing it through the IIS7 GUI):

Requested URL:  Matches the Pattern:  (*)  Using Regular Expressions (ignore case)
Conditions:  Match All:  Input:  {HTTPS}  Matches the Pattern:  ^Off$
Redirect URL:  https://sub1.domain.org/{REQUEST_URI}

Now, I've tried changing the Requested URL Pattern to: .*sub1.domain.org/.* but the regex tester in IIS7 says it doesn't match against https://sub1.domain.org - I don't understand that.

How can I keep the rewrite of http to https for sub1.domain.org, but not have any effect at all on sub2.domain.org ??

In our windows domain I am the Domain Administrator. I log into my servers with my domain administrator account via Remote Desktop.

Now, I just installed Windows Server 2012 and am working in it via RDP and discover that I cannot make changes to a text file because I don't have permissions. This problem extends to any file - not just text files, and the problem is not that they are set to read-only.

So just to make sure, I add my domain account to the local administrators group on that machine. I have also disabled UAC since I am behind a fancy firewall-router and have no security risks from local users.

So I go and check permissions on the c:\program files (x86)\ directory and see that the administrators group has no edit rights on that directory! Alas!

Then I try to give permissions to the Administrator's group and discover that I am not allowed (I'm Domain Admin!). To prove that, here is a screenshot. You can see that all the boxes are unchecked - they are actually disabled and I can't click on them.

Ah, but a funny thing is this: If I look at the Users group for that directory's permissions, I see that group has permissions to Read & Execute but not modify. They have more permissions than Administrators!

How can I give my Domain Administrator account rights to edit a text file in that directory? Is there some local group policy setting?

Note: This problem does not extend to folders in the root of C. It only happens in special Windows directories. But I never had this problem in other Windows Server versions.

In the Windows Server DHCP server, the only column that shows for "Reservations" is the "Reservations" column. That's not very helpful. It would be so much more helpful if I could see the description and the mac address.

When I go to "Customize Columns" there is no option to add anything to the view.

Is there any way to get the other columns to become available to the column editor, or is this one of those typical Microsoft feature-failures?

We are set up with a two-branch MPLS with a DCHP Helper on the Remote subnet. The DHCP service is running on a CentOS box.

So I have two subnets:

• HostRange: 192.168.0.1 - 192.168.1.254
• RemoteRange: 192.168.2.1 - 192.168.3.254

There are two problems:

1. When I tested this configuration at the host location, the computer I tested with pulled from a guest pool instead of receiving its assigned ip address.
2. The DHCP server doesn't like to see the same device in both subnets and throws an error saying it is listed twice.

Now, how do I specify the two networks in my config file? This is what I have come up with, which doesn't work:

shared-network CompleteNetwork {
    subnet 192.168.2.0 netmask 255.255.254.0 {
    option subnet-mask          255.255.254.0;
    option broadcast-address    192.168.3.255;
        option routers      192.168.2.1;
        #reserved pool for Guests (freely distributed)
    pool {
    range 192.168.3.101 192.168.3.150;
    }

    # ----A Laptop Computer for testing sake
    host TestSubject {
    hardware ethernet AA:BB:00:11:22:33;
    fixed-address 192.168.2.205;
    }
        #...
    }
    subnet 192.168.0.0 netmask 255.255.254.0 {
    option subnet-mask      255.255.254.0;
    option broadcast-address    192.168.3.255;
        option routers      192.168.1.1;

        #reserved pool for Guests   <------ ONLY RANGE DISTRIBUTED FREELY
    pool {
    range 192.168.0.101 192.168.0.150;
    }

    # ----A Laptop Computer for testing sake
    host TestSubject {
    hardware ethernet AA:BB:00:11:22:33;
    fixed-address 192.168.1.205;
    }
        #...
    }
}

[edit]

So I understand now that to have the same device on both networks I must specify a different host name. I also understand now that I don't need the shared-network part.

Also, Am I right to use that network broadcast over both subnets like that?

We have an MPLS consisting of two branches: Location1 and Location2.

I am using the Softperfect netscan to report all ip addresses and mac addresses of devices on Location1 where my workstation is located (subnet1).

However, I want to have the same report on my workstation (at location1) for all devices in Location2 which is on a separate subnet which I administer.

Now I know I could get that report via remote-desktop connection to a machine there and running netscan.

How can I get the report directly?

I would like a similar report:

• All connected devices
• device name
• ip addresses
• mac addresses

Somebody told me about using SNMP?

We have a two-location MPLS. I am told by the ISP that I can have a single DHCP server to service both branches.

But I don't understand this.

Consider this:

• Location1 (Host branch with the DHCP server)
• Location2 (Remote branch)

If I do a ip scan of the network (using Softperfect netscan), any devices that are at Location1 will show the router's mac address as their own mac address. So it seems that I cannot know the mac address of devices at Location2.

But can the DCHP server still assign ip addresses to devices at location2?

We have a semi-corporate environment with about 25 users. Most machines are Windows7 but there are some Macs on the network, too.

We want to set up some location (on a Windows server with lots of storage) where users can store their usual daily working files. This way, we can back up the entire storage drive and not have to run backups on each machine. The idea is that users will keep their important files here instead of their local machine.

Now, I've read about NASs but I am not sure that there is any reason why to use a special system rather than just a network file-share. If I'm not mistaken, even the Macs can access the windows file shares.

A NAS server would add another level of (unwanted) authentication. I am rather inclined to use just Windows file sharing. I don't need a media server.

Am I missing anything here?

In IIS 7 (.5) on my Windows Server 2008 r2, there are two places for error pages: ".NET Error Pages" under "ASP.NET" in Features View, and "Error Pages" under "IIS" in the same view.

It seems like the first does not do anything, but the latter does (in my web application).

Why are there two, and what is the difference?

Now, I know there are lots of samba questions (about 1400) on ServerFault, and I have browsed through about half of them at least, and not been able to use any of the answers to solve my problem.

We are installing CentOS 6.2 on a new, blank machine - clean install; it will run as a network server to host Asterisk.

I want to configure the machine so I have full, administrative access to root (I mean the "/" root) from my Windows workstation.

This will enable me to use my own, comfortable machine (and Notepad++) to edit all the configuration files. In other words, I should be able to open \\mylinux\etc\samba\ in Windows Explorer and then have full rights to edit smb.conf with my Windows Text Editor.

I have this working very well with CentOS 4, but can't get it working in CentOS 6.2. In the older OS version, there was a GUI for everything, but now I need to learn and do everything from the CLI. I still use the GUI for a few things that I haven't learned how to do form the CLI yet, so I will still make references to the GUI in my notes here.

Now that you know my problem and my goal, here are some details:

• smb is running and installed and set to runlevel 35.
• nmb is running and set to runlevel 35.
• the firewall is wide-open on eth0 and network is ON (I ran this command: iptables -A INPUT -s 192.168.0.0/255.255.255.0 -j ACCEPT)
• I have added my own user account on the linux box to the root group.
• that user account has the same username and password as my Windows computer.
• samba is configured to know the name of my Windows workgroup
• I am able to ping \\mylinux from \\mywindows just fine, and vice-versa, also.
• If I open Network in \\mylinux, I get an error saying: "Failed to retrieve share list from server" which I posted about here.
• If I do a net view from \\mywindows, then it does not see \\mylinux at all.
• samba is configured to share the root drive:

.

[root]
comment = Root Directory
path = /
valid users = @root all root group
invalid users = None
writeable = yes
browseable = yes

• also, in /etc/samba/smbusers.conf, I have made my entry:

  myuser = myuser

Now, you would think that I could access the linux share at this point. But when, from my Windows computer, I try to map the path \\mylinux\root\, I get an error saying the destination does not exist. On my old linux machine, I am able to browse even to \\oldlinux\ and get a list of shares. I can't seem to duplicate the functionality!

[EDIT]

Okay, I disabled the firewall completely, and now I can browse the files wherever I want to go. What remains is the permissions now to edit a file like smb.conf. In other words, my user account that I use to browse the files, which is in the root group, also needs root permissions. How do I get that?

Salvete! I have a machine running CentOS 6.2. In the GUI, if I click on "Network", I get a messagebox saying: "Unable to mount location - Failed to retrieve share list from server"

I can ping the machine from my windows computer on the network, and I can also ping the windows computer from the linux server. My Windows computers on the network all have their file sharing turned on and are able to see each other.

Samba is configured and running, nmb is running, and I can connect just fine to the box from my windows computer using Putty. In samba, I have specified the workgroup name.

How do I make the Windows Network visible to the Linux machine? I don't want to mount a share, I only want the Linux machine to see that there other computers on the network.

We have a server onto which we plan to install CentOS 6.2. The server will host Asterisk for our office, but is not a webserver.

If we install the minimal installation for CentOS - that is, no GUI for the OS, then that means that Asterisk will also not be able to be interfaced with a GUI such as FreePBX or Elastix.

I found this thread useful in the consideration: Should I use an Asterisk GUI? My thinking is to provide the GUI for folks who may have to succeed me and who do not know Asterisk so well as to manually maintain the configuration files.

Now, I understand that it is better for a server to run without a GUI. But if it is only meant to host Asterisk, then is it still a bad idea to install the GUI?

Salvete! I just installed CentOS 6 on a new box, and am looking for the "Server Settings" menu in order to configure SAMBA. I have a menu for System, and therein lie "Preferences" and "Administration" but no "Server Settings" and no "SAMBA". I suspect the tutorials I have been reading do not reflect the default layout of CentOS 6. Can anyone direct me, please?

Now, I can confirm that smb is installed, and that the service is definitely running. However, I followed the guide at http://www.reallylinux.com/docs/sambaserver.shtml, but my system does not recognize system-config-samba.

There are many items in the "Server Settings" menu that I am missing on my CentOS 6 installation. Maybe I have overlooked some package installation? I intend to use this machine as a server for Asterisk, so I need it fitted out correctly.
