Removing WSUS on SCCM Server Causes HTTP Error 500.19

Recently I was migrating my WSUS deployment off my SCCM server to a new standalone server so that I could enable Windows 10 and Windows Server 2016 updates.

After removing the role I started getting critical alerts for the management Point, Clients couldn’t be installed and I was getting 500.19 error from the SCCM IIS site.

SCCM MP Error

IIS Error

I had a quick search and found a blog post by Jörgen Nilsson that had the reason for the error.

When removing the WSUS role there are configuration settings that are written to the Applicationhost.config that reference a .dll file used by WSUS that is removed during the WSUS role removal. The Applicationhost.config is located under C:\Windows\System32\inetsrv\config

If we check the Applicationhost.config there should be an entry the same as below:

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

Running the following command will remove the references of .dll that is installed by WSUS

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

After running the above command the management point is back working and I can now access all SCCM URL’s
