We have a Windows Server 2003 server which is running SEPM. In the past few weeks, Liveupdate stops working and clients show that the antivirus definitions are out of date.
To maintain the server we access it via remote desktop, which fails with the message "The application failed to start c:\windows\system32\sysfer.dll was not found....."
If we restart the server, Liveupdate runs successfully, and similarly remote desktop also works without the above error.
The server then runs successfully for a random time (1-3 days) and then the above symptoms repeat. (ie liveupdate stops, no RDP).
We have ran a full Symantec scan, and Malwarebytes scan over the server, and no errors/malware is detected.
Searching the internet reveals a number of "product" for fixing missing sysfer.dll errors - we are reluctant to randomly choose one of these.
What would you suggest?
