On internal network I have a client and a server. Server is hosting example.com and fake.example.com that are also open to the internet through NAT. Any computer on the internet can access example.com or fake.example.com, but internal computers get redirected to router page when accessing either either site. How do I troubleshoot this issue, or what things should I take a look at?

Server: 10.10.0.10 with NAT route to public ip x.x.x.170 Client(s): 10.10.0.100 with NAT route to public ip x.x.x.174

example.com A record is set to x.x.x.170 so is fake.example.com

nslookup example.com and tracert example.com do indeed come back to x.x.x.170

I have encountered a situation where all GPO are applied for some user accounts, but only critical GPO get applied for other users because slow link was detected.

Our offices are on different coasts and connected via VPN tunnel. Until local server is available at each office, one of the offices is connecting to other for files, domain controller, etc. The link between offices is 10Mbps with 120ms ping.

I have already disabled slow link detection for workstations that seems to have this issues by configuring group policy slow link detection and setting it to 0 (Computer Configuration\Policies\Administrative Templates\System\Group Policy\Configure Group Policy slow link detection). Doing so does not help even after running gpupdate /force.

Shared namespaces are not available either and appear to be in offline mode. However, shares from each server in remote office can be accessed when avoiding namespace. On the other hand, dfs namespace through network mapped drive (policy applied) can be accessed with no issues.

Workstation: Windows 10 (also tried Windows 8/8.1) Server: Windows Server 2012 R2 Ethernet: OpenVPN Tunnel between two offices 10Mbps ~120ms ping

When attempting to install software (from network storage) on a domain joined computer two prompts show up asking for user credential. One is asking for Administrator account to install software and second is asking for account to access the installation file. Even when administrator account is used for both prompts there is still access denied error. Administrator account does have access to installation file and does have rights to install software.

Alternatively, copying file to a local machine first and then attempting to install it using administrator account credentials does indeed work.

Working with two Microsoft SQL 2012 servers in Always On High Availability configuration running on Windows Server 2012 R2. Setup works well and failover is almost flawless.

However, the software that connects to database (or high availability cluster in this case), is using sql user account that must be mapped to database. I have created said user on primary node and mapped it to database. On second node I have created same user but am not able to map it to database. Because of that, when failover happens the database is technically available but software can't connect because user is not mapped to database on second node.

I assume this is the issue because I am able to connect to high availability after failover using windows authentication.

I am running two SQL Servers 2012 (for Always On) under the same domain account and would like to know what are the downsides in doing so. Few articles that I have read prior setting up the servers suggest different domain account for each sql server and services it will be running. The downside to that method is each sql server must be also setup to have access to another sql server through that account. However, with single domain account all the sql servers already have the access since they are running under same account. Of-course, the biggest pitfall the articles pointed out is lower security, well, due to all sql servers sharing the account.

How critical is this, single domain account for all sql servers, in small environments and what are the other pitfalls?

I have been assigned a project where sql server is running on a single server with single raid 1 volume. This setup has worked fine until hardware failure resulted in about a day worth of downtime for small business. There is no strict budget for this project, but don't want to go too crazy.

First option I looked at is SQL Server Cluster with two nodes. Hardware is already available and I have tested the setup in test environment with a great success. However, that still leaves me with storage as a single possible point of failure.

What would be a good option to go along with sql server clustering failover?

Software: Windows Server 2012 and Microsoft SQL Server 2012

Note: I do understand that besides storage failure there is also a possibility of network card or switch failure that would cause as much downtime, however, just for the sake of it let's assume it is taken care of.

I have a machine that was running software windows raid 1. Somehow, after restart raid configuration failed and now two drives are separate volumes. I can't find an option to restore raid configuration or create new raid 1 setup without erasing both drives.

How do I restore previous software raid 1 configuration?

Edit: Drives were in mirror setup for storage, not boot. Both drives are now dynamic, simple volumes.

I have a OpenVPN Server running on pfSense 2.0.3. I can't find an option to add WINS address for VPN connections. I tried going to VPN > OpenVPN > Server > Edit server > Client Settings > NetBIOS Options and enabling it. However I must have configured it wrong because of multiple restarts I still can't access computers via name (\SERVER).

How do I set WINS server for VPN clients?

I have an option to create a single raid volume and partition it in the OS, or create multiple raid volumes (one for each partition)?

1. What are the performance or access time differences between two?
2. Are they handled differently? If so, what are the pros and cons of each?

I have a zip archive containing installed windows xp embedded operating system. How can I copy files onto HDD to make it bootable?

I went to disk part, converted hdd to mbr, created primary active partition and copied files over. Still can't boot.

VMWare ESX/ESXI running with AMD 12core @2.2GHz. Intel 6core @2.4GHz

In resource pool, with amd cpu I should see 26.4GHz available. Now it's interesting what will be shown with Intel CPU? Am I gonna get 14.4GHz resource pool or 28.8GHz?

In my last questions I didn't make myself clear, so I will do my best to explain it.

I have a server with esxi 5 installed on it. I am not able to setup hardware raid atm, and need a workaround.

From previous question I have been told to setup a raid for guest-os (don't confuse with hardware/software raid for/on host). I wasn't able to find any information about this, nor found any option in guest-os bios.

Help appreciated.

Edit: I have two drives setup as datastores. Each drive/datastore will host one image file for guest os

I have a vmware esxi 5 running on a server with ssd and two hard drives. The server comes with software lsi megaraid and intel rapid storage raid. Neither of them work with esxi.

I need to somehow setup a fakeraid inside virtual machine to keep a copy data on each drive (raid0).

Is it possible to do so?

Host OS has one nic with 4 static IP address x.x.x.250-x.x.x.254 I have installed Ubuntu as a Guest OS with bridged networking. I would like it to have static ip x.x.x.255

As I mentioned earlier, host os has ip set manually. I set ip manually for guest os (ubuntu server) but it doesn't seem to be able to ping any ip.

Your help is appreciated

Edit: Host OS does not use IP x.x.x.255

Recently moved local server to a datacenter. It is used for small file storage, database and thats about it.

I am trying to setup VPN there, which I have never done.

I tried setting it up while following this tutorial: http://www.techrepublic.com/article/configure-a-windows-server-2003-vpn-on-the-server-side/5805260 Worked out good but I do not need NAT server there.

Then I also tried setting up only VPN Server (Remote Access option). Worked good but one thing. While client is connected, it looses internet connection.

Two questions from here.

1. If VPN&NAT setup is used, does that mean client is using internet connection through VPN Server?
2. How can client keep internet connection while connected to VPN Server (which is setup as Remote Access)?

I have Litespeed Web Server Enterprise v4.0.1 installed and configured. I decided to check phpinfo() and it turned out that I have php 4.4.9

I checked in LWS Admin panel and there are three script handlers. One php5 another php 4 and just php. Regular php is set to php5. But howcome it still uses php4?

Will server switch to php5 automatically when needed?

Let's say I wanna have a MongoDB Server with 5 shards on one machine and each shard having replica set of 3 servers.

Would that increase performance? What are downsides of this?

I have following setup: a windows server 2003 dedicated server with tho nics. One is connected to internet (no modem/router), and second one is connected to private network. Server has DHCP server installed on it and internet nic is being shared for internet access.

The problem is sometimes server loses connection to the internet, so same happens to private network. So far I can manually fix it by releasing and renewing IP address.

What could be the cause of this problem? DHCP lease from ISP?

Thanks

I am owning a small company and we have purchased a server to setup few server applications on it as well as other software.

We would like to setup our network in following way

Internet<->WindowsServer2003 as router<->Switch<->Office Computers

Server has two nic interfaces and we have 24ports 1GB network switch connected to one nic and internet connection to another nic. Our ISP is Frontier and we have Fios 25/25. We get network cable out of ONT box directly connected to our server. There are no modems/routers.

Setting up DHCP on windows 2003 is easy job but we would like to have the ability to port forward some ports from office computers.

I have some knowledge in networking but not as much. How could I setup FHCP server on win2k3 with the ability to port forward some ports to office computers?

Thank you for your time
