Have been bashing my head against the wall on this one and need some help.
ESXi running guest OS of Windows Server 2003 Standard SP2. This is running terminal services with Office 2003 SP3, IE7.
After a few days of use the server begins to run slow, takes a long time to log on etc.
Users complain of hanging apps, slow to open attachement etc
What I have done:
Ran up a copy of Process explorer and found SVCHOST.exe to the be problem, Narrowed it down to Terminal Services taking up the CPU usage.
Read up on some forums about similar issues, tried disabling Windows Update (as suggested but I didn't think it would work due to the Terminal service causing SVCHOST.exe to run high)
Tried to get all users to log off and see if the problem goes away (as in maybe the TS was overloaded) But this made no difference, with only me as the admin logged on the CPU still spiked at 100% for extended periods of time.
So far the only "fix" is to restart the server. Not ideal to have to do all the time.
Has anyone seen anything like this before? Or does anyone have any bright ideas for me to try next?
The only thing that possibly is causing the issue would be a rootkit, but I would expect the issue to happen straight after a reboot if that was the case.
Any ideas would be great!
