Server 2008 R2 Keeps freezing after latest patch cycle


We have a  server running server 2008 r2 with file storage, and SNMP for monitoring the DSET system variables, and IIS for office FTP rolls installed.

After this month's patch cycle the server became very unstable in the following weeks.

Any ideas as to which patches would cause issues with the server?

Was thinking that the Dell DSET service could be conflicting with something as the service has frozen several times.

File system checks out good, event log doesn't show anything out of the ordinary.

Hardware is a Dell T620 with a PERC H310 running RAID.  Dell server admin shows everything working well before the system freezes.

Without any more details, like event log entries that you've discovered on this machine, there isn't much to go on here.

Be that as it may, perhaps you're also completely stumped as well as to what is going on.

Something that is quite useful that is enabled by default in Windows client OSs is the Reliability Monitor. Unfortunately, that is disabled by default on Windows server OSs. provides guidance on how to enable Reliability Monitor on a server OS. Maybe this will help flesh out the problem.

Otherwise, you can go in to Installed Updates (from the Search bar) and uninstall all the updates that have been applied since the time the server became unstable and see if it stabilizes again. I would recommend before removing them, jot down all the KB articles and check with your other software/hardware vendors (google, of course) to see if there may be known issues with a particular update with a particular vendor.
