SharePoint 2010 Services crashes post windows OS Upgrade
Attempted to upgrade one of my development machines from Windows 2008 Server Standard server into Windows 2008 Server Standards R2
And got a slew of errors (but thank God for VM snapshots )
Here are the errors and the fix.
OWSTimer.exe Timer service crashing.
System.IO.FileNotFoundException Occurred in SPUCHostService.exe
System.IO.FileNotFoundException Occurred in SPUCWorkerProcessProxy.exe
System.IO.FileNotFoundException Occurred in WebAnalyticsService.exe
System.IO.FileNotFoundException Occurred in OWSTimer.exe
It is mainly a version incompatibility with the Windows Identity Foundation
You need to install this version, of Windows Identity framework ( the one that matches the new OS level)
Windows6.1-KB974405-x64 downloads from TechNet.
You can force install this package using the SharePoint ISO or deployment media , (rerun the Prerequisite installer)
And of course (REBOOOOOOOOOOOOOOOOOOOOT)
(If you have multiple Servers in the farm .you will need to do the same on each member server no matter what the role is .)
[Run the SharePoint Products Configuration wizard]
Also make sure you run the windows updates and install all the needed updates.
Best of luck.
