WSUS Not Downloading Updates

During a recent WSUS upgrade from an old server to a new virtual machine running Windows Server 2008 R2, I saw an issue with the server not downloading updates correctly. The server appeared to synchronise correctly, but then no updates were downloaded.

We originally saw an issue like this when we started using Microsoft Threat Management Gateway, and the errors reported in the application event log on the new WSUS server were the same, namely:

Error 10032: The server is failing to download some updates

Error 364: Content file download failed. Reason: The server does not support the necessary HTTP protocol. Background Intelligent Transfer Service (BITS) requires that the server support the Range protocol header.

Microsoft KB article 922330 provides a solution for this specific issue, in our case we’re using a pre-existing SQL Server, so went with

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

However this didn’t solve the issue.

In our case, the existing instance of SQL was on another server, so the command should have been:

"%programfiles%\Update Services\Setup\ExecuteSQL.exe" -S SQLServerName\Instance -d "SUSDB" -Q "update tbConfigurationC set BitsDownloadPriorityForeground=1"

Once the revised command had been run and the WSUS server restarted, the update downloads started automatically.
