Nothing like a service pack to fix all your problems, or in the case of SCCM 2012 SP1 create some new ones for you.

After running a SP1 upgrade I was wondering why my OSD process was failing when attempting to install applications.

Checking the Site Status>Distribution Point  this was now reporting as critical and the errors I was getting referred to:

‘Site Component Manager failed to install this component, because it either can’t find or configure WSUS.’

followed by

‘Site Component Manager failed to reinstall this component on this site system.

Solution: Review the previous status messages to determine the exact reason for the failure. Site Component Manager will automatically retry the reinstallation in 60 minutes. To force Site Component Manager to immediately retry the reinstallation, stop and restart Site Component Manager using the Configuration Manager Service Manager.’

It seems that my WSUS install has been reset from port 8530 (see this post) to port 80.

To remedy the problem go to the Administration workspace. Choose Site Configuration>Servers and Site System Roles. Right click the Software Update point and select Properties.

Change the ports back to 8350 and 8531.
