I had a machine with WSUS already installed and configured. I installed SCCM 2012 R2. I realized afterwards that WSUS should not have been installed or at least not have been configured. Now that this has happened my management portal is showing a critical error (the only service believe it or not). I suspect is has to do with the WSUS and IIS configuration. I removed WSUS from the server but how to I get management portal re-setup or reconfigured. I tried to do a repair of the server but it does not correct the problem.
