SCCM Management Point Shows Error 500 After Removing WSUS

Let me guess? You uninstalled the Software Update Point from SCCM and removed WSUS from the server… now your SCCM Management Point, which was likely on the same server as WSUS, is showing critical in SCCM and reporting IIS 500 errors within the SCCM logs. When uninstalling WSUS, sometimes the configuration information does not get removed from the IIS ApplicationHost.Config file. Because of this, IIS shows error 500 when it cannot locate suscomp.dll.

You can test this theory by opening Internet Explorer and browsing to http://[mpservername]/SMS_MP/.sms_sut?mplist. If you are able to successfully browse to this address, you will see an XML file with a list of management points. If, instead, you see an IIS 500 error, you can check to see if this is your issue.

Taking a look at ApplicationHost.Config, you will find the below entry:

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

In order to remove this entry from IIS, open Command Prompt as an administrator and enter the below command:

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

Once this command is run, a confirmation of the removal will be displayed. Go back to http://[mpservername]/SMS_MP/.sms_sut?mplist and confirm that you see the XML file. If you do, your Management Point is back up!
