My fresh install of WSUS 3.0 SP1 was downloading at pathetic speeds. I’d let it run all day and pulled down only 700MB (of 13,465.69MB).

Googling this problem came up with few results, most of which talked about WsusDebugTool.exe, which unfortunately does not work with WSUS 3.0.

The solution: http://support.microsoft.com/kb/922330. I found it on a random forum, the kb article title is awful, but the insides work.

From the article:

If you are using WSUS 3.0 with a Windows Internal Database that was created by a default WSUS installation, type the following command (all one line):

%programfiles%\Update
Services\Setup\ExecuteSQL.exe -S %Computername%\MICROSOFT##SSEE -d
"SUSDB" -Q "update tbConfigurationC set
BitsDownloadPriorityForeground=1"

Restart the Update Services service. To do this, follow these steps:

1. Click Start, click Run, type services.msc, and then click OK.
2. In the Services dialog box, right-click Update Services, and then click Restart.
