I have a pretty serious immediate problem. We have a SBS2008 server that is a bit (too) old. It has a 500GB RAID 1. We have been running out of disk space which has caused Exchange to stop receiving email. I've gone through all the recommended log cleanups, which helped for a while, but that's no longer working.
In examining the drive folders, I found that the C:\WSUS folder was taking 188GB!, nearly half the space. I ran Administrative Tools > Windows Server Update Services> expand my domain > Options > Server Cleanup Wizard. That ran for a couple of hours with no apparent change on the progress bar, whereupon I canceled the cleanup (it never terminated) and rebooted. That did seem to help because we were able to receive mail ... for a while.
Immediately after rebooting I restarted the Cleanup Wizard. Again, that ran for many hours, but eventually aborted with a database error (sorry, didn't record that). The disk is again too full to receive email. I've restart the Wizard a 3rd time. It is running as I write and has been running for about 2 hours. It is sitting on "Deleting unused updates..." with the progress bar stuck at about 30%. Sadly, checking the size of the C:\WSUS folder shows it is now 192GB -- even bigger! Either the cleanup is growing the folder (work files?) or more updates are downloading.
HELP! We are planning on replacing this SBS2008 system next quarter for obvious reasons. Meanwhile, I need to get email delivered TODAY. Can I manually delete stuff in the WSUS folder (I haven't dared try)? In fact, I'd be OK with disabling Update Services and deleting this entire folder. The workstations will all get back up to date when the Server is replace.
