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)
