Great tutorial, thanks this has saved me hours of work...
I do have an issue with this part though, I am only installing onto one server which already has WSUS installed on it so skipped the install part of the WSUS server. I have added the role to SCCM 2012 and ticked the software update-based client installation and reran "check for updates" on my test machine (i have configured it to a group with only one computer in so far) and it finds the update but it fails to install with the error "No valid source or MP locations can be identified to download content from. cmSetup cannot continue..
Any ideas where I need to look to rectify this?
Cheers
