WSUS 3.0 SP1 Tips

1) Make sure Disk Quotas are disabled on the drive where you host the WSUS update files. Otherwise the MMC snap-in will fail with an "Out of disk space" error.

2) If you install WSUS 3 SP1 on port 8530, the SelfUpdate virtual directory isn't created. You will have to manually create the SelfUpdate virtual directory and point it to C:\Program Files\Update Services\Selfupdate (leave the default permissions)

Troubleshooting

If you are having trouble with AutoUpdates, the WindowsUpdate.log file is very handy, its located in:

C:\Windows\WindowsUpdate.log

Clients "Not Yet Reported"

If you have clients that refuse to report to the WSUS server try the following:
1) Stop the Automatic Updates Service

net stop "Automatic Updates"

2) delete

%windir%\SoftwareDistribution

3) Start Automatic Updates Service

net start "Automatic Updates"

4) Run:

wuauclt /detectnow /resetauthorization

The nasty client should report to the WSUS server shortly there after.
