I noticed that I was getting a lot of red crossed under my site components and that my default website was chucking out the following error after a WSUS install on the local SCCM server.
HTTP Error 500.19 – Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.
This was also the case when trying to access http://localhost/ccm_client and application portals.
I had a look at the ApplicationHost.config file and noticed that suscomp.dll was installed by WSUS.
1. Go to C:\windows\system32\inetsrv\config and locate the ApplicationHost.config file
2. Open it with notepad and look for the following lines below
scheme name=”xpress” doStaticCompression=”false” doDynamicCompression=”true”
3. The following command needs to be run to disable the suscomp.dll that was installed when the WSUS server role was installed, Im not 100% sure but from what I could see compression schemes are in every application pool and when WSUS x64 was installed the suscomp.dll chucks out the 500.19 error when its trying to load the x86 application pool. So from an elevated command prompt running the following.
%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /-[name=’xpress’]
4. If you need to re-enable this just change it slightly and run this command.
%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /+[name=’xpress’,doStaticCompression=’false’,dll=’%windir%\system32\inetsrv\suscomp.dll’]
