With the recent update to the IMF signatures for Exchange 2003 I got caught in a never ending circle of installation prompts. The new update would install, then last months update would ask to install and so on and so on. After realizing what was going on I went in search of answers. The 1st thing to try was to reset the Windows Update Cache. It can be done by plopping the code below in to a bat file and running it on the offending server.

net stop bits
net stop wuauserv
regsvr32 /u wuaueng.dll /s
del /f /s /q %windir%\SoftwareDistribution\*.*
del /f /s /q %windir%\windowsupdate.log
regsvr32 wuaueng.dll /s
net start bits
net start wuauserv
wuauclt.exe /resetauthorization /detectnow

This did not solve the issue for me. I turned out that my WSUS server did not mark the old IMF update as declined. Once the old update’s status was changed to declined the update cycle was stopped dead in its tracks.
