Windows Server 2008 File Server inaccessible from clients

Zones: Microsoft Server, Computer CPU Processors, TCP/IP

Tags: Microsoft, Windows Server, 2008

I have recently installed a new domain for a client, based mostly on Windows Server 2008.

The client has four sites - 3 remote sites have a single 2008 DC on site and are linked to the main site, via VPN, which has a 2008 DC acting as the file server, and a 2003 DC hosting Exchange 2007 SP1. There is also a 2008 Terminal Server here.

Every PC in the domain connects to their local DC and then RDP's to the terminal server and works through there.

Over the last few days, we have found that it takes around 20 minutes for the clients to log in to terminal server. Investigation of this found that the File Server could not be accessed over the network (and the users Termina Server profiles and home drives are stored on the file server). I can log into the terminal server through RDP, but again this can take 15 to 20 minutes to complete. The only thing I can then do is restart the machine to get things working again. I think the server may be crashing as well, as the moment I click restart a continuous ping from another machine will suddenly drop - you would expect there to be at least a few replies while it shuts down and restarts.

The only error I can find in the event logs is from the HP Foundation agents which says "The Host Remote Alerter detected an error while attempting to retrieve data from key = CompaqHost\OsPerf\Component\LogicalDisk in the registry. The data contains the error code."

I cannot find this error anywhere on the internet, but is it indicating that there is a problem with the CPU?

I know the client locked their server room over the weekend without making sure their air-con was on and the servers all shut down due to over heating - could the CPU have overheated to the point it was damaged?

Otherwise, I am at a loss to explain what is going on.

It appears it was not directly endpoint but when we pushed out the client to the clients It gave thousands of virus warnings accross the network. It looks like Endpoint was shutting down the server to protect it from attack. Now the clients are cleaner, the server has become more stable. Anyway given that your answer would of solved the problem you deserve some credit :)

Comment by dimante

Thanks and glad that your clients are cleaned up as well. That can be a horrible situation.

I'm not sure that's what's causing it in the end - prior to Thursday, the server ran abasolutely fine for a week or so. Then on Thursday afternoon, Friday and today it started randomly locking up again. There's nothing in the system logs or the Endpoint logs to suggest that it is causing the problem, no virus alerts on any of the machines etc.

It's driving me mad...

How about updating symevent ?

Comment by onlinecomputing

I finally got to the bottom of it - it was the Desktop Windows Session Manager Service failing to unload people properly. Disabled this service and rebooted, haven't had a problem since
