Hi Guys,

I have a Terminal server farm of 18 servers which get used by 80% of company. Every now and then random server hangs and all the users session on the that server hangs as well. Though I can ping the server but when I try to RDP to that server, it hangs at Welcome screen.

Then I have to physically restart the server and things come back to normal.

I did check the event logs at the time when the server hung. There are errors with Event ID: 7011

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the Spooler service.

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the NlaSvc service.

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the CryptSvc service.

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the Schedule service.

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the ShellHWDetection service..

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the seclogon service.

A timeout (30000 milliseconds) was reached while waiting for a transaction response from the UmRdpService service.

The Environment is
Windows 2008 STD SP2 on HP BL 460c G6 servers
Printers are HP (mainly)
Users are connecting via Windows XP Sp3

I have also upgraded to latest firmware and updates.
Also, applied the patch mentioned in http://support.microsoft.com/kb/972596/

There are quite a few articles on Google but none of them worked out so far for me.

any help would be appreciated.

Thanks
