Uninstalling WSUS on Primary Site server causing HTTP Error 500

I have ran into this a couple of times now when moving site roles in Configuration Manager 2012. When uninstalling the WSUS server components from in this case the Primary Site server to move it to a dedicated server instead the Management Point on the Primary Site server started giving HTTP Error 500 Internal Server Error:


This was caused by the removal of the WSUS role on the server which removed almost all the files installed by the Windows Update Services but not the configuration written in the ApplicationHost.config file. The Applicationhost.config file tries to call the .dll installed by the WSUS Server but no longer exists on the system.

From the Applicationhost.config file:

<scheme name=”xpress” doStaticCompression=”false” doDynamicCompression=”true” dll=”C:\Windows\system32\inetsrv\suscomp.dll” staticCompressionLevel=”10″ dynamicCompressionLevel=”0″ />

<scheme name=”xpress” doStaticCompression=”false” doDynamicCompression=”true” dll=”C:\Program Files\Update Services\Webservices\suscomp.dll” staticCompressionLevel=”10″ dynamicCompressionLevel=”0″ />

Running the following command will remove all references to the module installed by WSUS.

%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /-[name='xpress']

After that the Management Point is up and running again.
