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)

Testing & Troubleshooting
If you are having trouble with AutoUpdates, the WindowsUpdate.log file is very handy, its located in:
C:\Windows\WindowsUpdate.log
Make sure the WSUS server is reachable via SMB and http(s) Use Windows Explorer to browse to the following UNC path:
\\WSUS.domain.tld\WsusContent
Use a web browser to browse to the following URL:
http://WSUS.domain.tld:8530/selfupdate/wuident.cab
or for https:
https://WSUS.domain.tld:8531/selfupdate/wuident.cab
If you are prompted to download a file then WSUS/IIS is configured correctly.
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
del /s %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.
