I recently started with AWS and I need to stop/reboot some EC2 Windows instances. The instances are with EBS volumes.
Is there any difference if I use the Shutdown/Reboot Windows option vs Stop/Reboot from the AWS Console?
I am unable to add Outlook account for an on-premises mailbox for in a Hybrid Office 365 solution.
Mail flow works just fine. The autodiscover records are pointing towards Office365 and all of the domain checks are green. It is only when I try to add an Outlook account the search hangs with "An encrypted connection to your mail services is not available"
This is true when adding the mailbox both from inside and outside our network organisation.
I'be been searching this on google, and everywhere I can find only problems relating to adding a migrated mailbox to Office 365, and this problem that I have is just the opposite.
Please advice, I am going desperate.
Edit: I also tried to use the MS Remote Connectivity Analyzer. The last error that I have is:
We were unable to get account settings after a domain redirection.
I have exchange server hosting emails for multiple domains. How can I make the Get-MailboxStatistics cmdlet to display mailboxes and sizes only on mailboxes that end with a certain domain?
Something like Get-MailboxStatistics WHERE EmailAddressEndsWith *emaildomain.com
Thanks.
Migrating a VM with VMware is easy, from a Workstation to vSphere cluster it can be done with a VMware Converter.
I have little experience with Hyper-V though. There is a VM on a Hyper-V on Windows 8.1 and I have to move it to a Hyper-V Cluster.
How can I do it? Is there a tool like Hyper-V Converter or should I just move the VHD and recreate the VM on the Hyper-V cluster?
I've never seen anything like this before. I connected to a vCenter with two hosts. The first host has a single parent entity with 33 VMs. They are all stacked together and I cannot expand the entity. If I click on it they will appear on the right main console panel. It is neither a folder nor a vApp. You can see on the image what I mean, because I don't know any other way to rephrase my question.
I am installing a Sonicwall firewall into my organization. I've connected the Sonicwall with the Active Directory domain, however now on the status page of the appliance there is a huge warning:
WARNING: LDAP is being used without TLS - this is highly insecure.
I understand that connection between the FW and the DC is made with clear text and although this is not much of a problem because the Sonicwall and the Domain Controllers are in the local network and in the same subnet, we still want to encrypt the traffic to comply with our regulations.
As I made my search on other forums people are mentioning that I need to apply a certificate to the Domain Controller as per this MS article which is also mentioning the installation of AD Certificate services.
Is there any other way to do encrypt the LDAP traffic without installation of the additional role (AD CS) on the Domain Controller? Installing additional role to the Domain Controller, just for one simple task seems like an overkill to me - like nailing a needle with a sledgehammer.
Also If I am really to install and deploy a Certification Authority to our organization what would be the impact on it? I don't have experience working with it, so are there any implications and/or problems for which I am to be aware of?
The LCD display panel at one of our HP C3000 blade chassis is stuck and I am unable to close it. See the image below. I am somewhat reluctant to push harder, as I am afraid that I might do additional damage to the chassis. Does anyone had a similar problem? Any options to resolve would be greatly appreciated.
On the vsphere web client I have a strange problem with one of my datastores as it's displayed capacity is incorrect. Originaly it had 1TB of disk space. After I increased it's capacity on 1.4TB the next day it reverted back to 1TB.
The particular datastore in question (MSA_VD005) is located on HP MSA Storage. Originally it had 1TB of storage and from the MSA Array I increased it at 1.4TB, and after that I increased its capacity from the vsphere web client. (Standard procedure as i do always)
The very next day I've noticed a Datastore usage on disk alarm in the web client. When I checked the datastore it had 1TB of space, as if I never increased it.
If I rescan all storage adapters on the hosts, it will show a correct value of ~1.4TB again but If i click the Refresh button it will revert to 1TB again.
In order to verify all of this I logged in with SSH on one of the hosts and verified that the datastore size is indeed ~1.4. It is just that the vsphere web-client somehow pulls wrong value and generates warnings based on that value.
After rescan of the storage adapters:
After clicking the refresh button

I have a situation where I need to modify an enforced group policy object, however due to the sensitive nature I must test my results first to one test user.
In order to do this I plan to create new policy object with the same settings, apply the correct modifications there, and then test it only to a particular test user (you get the idea).
Because the main GPO in question is enforced, I have to somehow make the test GPO win over the main GPO?
Will the test GPO win over the enforced GPO if I put the test GPO above the main GPO, enforce it and with the security filtering apply the test GPO only to the test user?
I have a situation where I need to add a host to two vCenter servers. The vCenter servers are divided into two different networks and are not in a linked mode i.e. the other vCenter server belongs to a partner company of us and the host is a shared host between us.
The host is already a member of their vCenter server.
I already configured two management IP addresses of the ESXi host and it is accessible from both networks. However, I don't know if it is safe to try to add the host to our vCenter server as well.
In the next few weeks I should migrate a SBS2003 DC to Win2008R2 on a different server.
I found this guide here: http://demazter.wordpress.com/2010/04/29/migrate-small-business-server-2003-to-exchange-2010-and-windows-2008-r2/
That guide is pretty much what I need to do i.e. that is almost the exact environment that should be migrated. However I have a few questions regarding the migration process that I thing some of you that had done it before will know to answer.
- First of all what known problems may arise during the migration. (Some previous experiences/stories will be helpful)
- As I know according to the Microsoft KB I need to first prepare the Active Directory with the
adprepcommand. Can this command somehow cause any problems that will require for us to restore/rebuild the domain? - Also another thing that I noticed is raising the Domain Functional Level. Can this thing also cause some problems?
I know and from what I've read on other forums there really isn’t any good documentation on what to expect. But I decided to give it a try and to ask here from more experienced Windows admins that have done this before.
We have three CentOS 5.9 VMs on an ESX3.5 host.
Because of the nature of the services we provide it is required that the NTP time is synchronized and the time is correct on all three of them.
However one of them constantly drifts back each day for about 66 sec. So far none of us seems to understand as why is this happening.
We included the possibility that the VM may be somehow pulling the time from the host, however all of the three VMs have identical configuration settings and they did not have VMware tools installed.
Although I realize that this is probably a question of an internal matter and not to ask for on a forum, I would appreciate if anyone of you knows some CentOS NTP diagnostic routines that will help me to diagnose the problem and find a reliable solution.
I thank you for the assistance.
Today we've stumbled on a very awkward situation with our VMWare Server. The server is with ESX 3.5 that has a 1Gbps NIC.
We bought a brand new managed Cisco Linksys switch with 10/100Mbps interface ports but when we plugged the cable in one of the ports the link simply does not wanted to activate :S...
Does anyone with more VMware experience have ever had similar problem? From what I know is that 1Gbps NICs are backwards compatible with 100Mbps switches.
This is what we've tryed so far but with no success:
Tryed to modify the
/etc/modules.conffolowing the guide from this article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=813After the changes I have restarted the networking services using
# service network restart,# service mgmt-vmware restartand# service vmware-vpxa restart
It seems that no matter how many times, or whatever approach/method (GUI or Shell) we try to change the speed and duplex of the network adapter and to force it to 100mbps it only accepts 1Gbps ..
I am starting to go nuts :@
I was recently configuring a WSUS server. However I am not sure if I've set up correctly (WSUS isn't an everyday tool at the place where I work).
I've been wondering, Is there a command (or a tool) in Windows 7 that can be executed on a client machine and will verify the location from where the client is pulling the updates?
UPDATE:
It seems that the WSUS is working. The GPO is showing the clients as Kyle Brandt suggested.
However I just want to verify one more thing. Here's more info on the GPO i've created in order to distribute the updates.
Corect me if I'm wrong, I am not sure about Target group name for this computer option. Does it want as a value of the names of the AD Groups or the names of the WSUS groups? I wasn't sure so I include both of them - from the image you can see that I have put inside the relevant AD Groups and WSUS Unssigned Computers group
I am very weak on unix shell scripting. Is there a way to create Unix shell script which will start on server boot time only, and will execute the following commands in order:
# cd /mysql
# ./bin/safe_mysqld --user=root &
# ./support-files/mysql.server start
The longer story... On a HP-UX server I've installed Mysql. However the client wanted the server to be installed in /mysql instead in /usr/local/mysql/ which is the standard location. During the last week I've been struggling to set the mysql daemon to start automatically on server boot time.
I don't know what is the problem, but so far the only way to start the server is by using the above commands.
UPDATE: 07.02.12 15:23
This is a short output from the server boot when it starts the processes:
Start MySQL Server .................................................. OK
...
However after i enter ps -ef I can easily tell that it is not started:
# ps -ef | grep -i mysql
root 3074 3056 0 15:26:53 pts/0 0:00 grep -i mysql
#
And this is how it should look like when i start the process:
# cd mysql
# ./bin/safe_mysqld --user=root &
[1] 3123
# Starting mysqld daemon with databases from /mysql/data
#
# ./support-files/mysql.server start
Starting MySQL
SUCCESS!
#
# ps -ef | grep -i mysql
root 3139 3123 0 15:27:19 pts/0 0:00 /mysql/bin/mysqld --basedir=/mysql --datadir=/mysql/data --u
root 3123 3056 0 15:27:19 pts/0 0:00 /bin/sh ./bin/safe_mysqld --user=root
root 3171 3056 0 15:27:59 pts/0 0:00 grep -i mysql
#
Now I think that it is more clear why I want to create a shell startup script and actually FORCE the starting of the process with those commands.
THE STORY:
(If you don't like to read much, down below is the question :) )
Where I work we have two HP RP2470 servers same hardware same number of hard drives same everything :).
One of them is a production server and runs HP-UX 11.00. The poor ba***rd hasn't been turned off for years and now I have to make a clone of it on the other server - just in case, for redundancy.
The problem is simple (or not simple) as I have to make the the other server exactly the same. However the old version of OS (UX 11.00 is a history now) and the old software running on it, have made my task almost impossible.
On the production server there is also a cloning/recover utility Ignite-UX. I tried many times to create a recovery tape with it. Then when I load the tape on the backup server, it succeeds with the loading of the tape (no errors no warnings) but on the next restart it fails to load the OS :S and drops into HP`s ISL prompt.
---
THE QUESTION:
Is there an alternate way to create a clone of the Unix System?
The environment is:
1. 2x HP RP2470 Servers (non-Intel), same hardware, same number od HDDs (two each of them) same everything.
2. OS running: HP-UX 11.00
The production server has to be cloned without downtime - sadly :( as I hope that they will reconsider on this one
For example (like on Windows platforms),
if you try to copy an entire HDD with Windows inside on another HDD, and then put that HDD on another PC it will still work, as long as the hardware is the same.
Can I do something like that with a Unix system? Can I somehow COPY the contents of the entire HDD, put those on another HDD, and then just load the HDD into the other server? (If you haven't read the story the servers are exactly the same)
Will it work? Can it be done with ordinary commands like cp or dump or something like that? Does any one have a similar experience?

I have a HP-UX server with two instances of Mysql.
The first one was the original and was located in
/mysql, and keeps its database files in/mysql/data/The second one I have installed by mistake and is located in
/usr/local/mysql, and it keeps its database files in/usr/local/mysql/data/
Now the problem is (i guess because of the new installation), when i issue the command to start the mysql daemon (the original one located in /mysql) i receive the following message:
... so as you can see I start the daemon from the old instance of mysql but when it starts it is now using the new installation database files.
How can i change the path (what file i should edit) in order to make the daemon to point to the old database files that are located in /mysql/data/?
On a HP-UX OS I have a backup on a magnetic tape created from the SAM. Everywhere I read the instructions to list-verify the contents of the tape is to use the TAR program:
#tar tvf /dev/rmt/[tapefile]
I've created a new directory /tape with 777 permissions, but when I execute the above command it gives me an error message:
#pwd
/tape
#tar tvf /dev/rmt/0mn >> listtape
Tar: blocksize = 2
directory checksum error
Going after the blocksize error I used another version of the command with the "b" flag:
#tar tvb 2 /dev/rmt/0mn >> listtape
directory checksum error
Anybody have a sugestion? How can I view the contents of the tape? What does this error means?
Does any one knows a way to configure a cisco router with multiple gateways - multiple gateways of last resort?
I've tried adding a gateway of last resort twice (with different metric) but only one is shown:
Router(config)# ip route 0.0.0.0 0.0.0.0 2.2.2.2 10
Router(config)# ip route 0.0.0.0 0.0.0.0 3.3.3.3 100
And the show ip route output was:
Router# show ip route
Gateway of last resort is 2.2.2.2 to network 0.0.0.0
2.0.0.0/24 is subnetted, 1 subnets
C 2.2.2.0 is directly connected, FastEthernet0/0
3.0.0.0/24 is subnetted, 1 subnets
C 3.3.3.0 is directly connected, FastEthernet0/1
32.0.0.0/30 is subnetted, 1 subnets
C 32.2.2.0 is directly connected, Serial0/2/0
S* 0.0.0.0/0 [10/0] via 2.2.2.2
The point is that i cannot see the other route with higher distance metric?
Anyone has a sugestion?
I mean will this config work if the link on 2.2.2.2 fails? Will the router choose the other network 3.3.3.3, if the link 2.2.2.2 fails?
Everywhere I read about the FSMO roles it is written that after it is seized the FSMO role can not be transferred back to its original server.
Did someone knows why? Lets say that I seize the Schema Master and then I try to transfer it back? What will happen?
Of course that this does not apply to PDC Emulator or the Infrastructure master.
