I have successfully imported the following hotfixes mentioned by KB2775511 into WSUS and can see them there, but after trying a sync via SCCM i do not see them in the list of updates:
http://catalog.update.microsoft.com/v7/site/Search.aspx?q=2732673
http://catalog.update.microsoft.com/v7/site/Search.aspx?q=2728738
http://catalog.update.microsoft.com/v7/site/Search.aspx?q=2878378
Any idea how to figure out why SCCM isn't showing them? Possibly a log file to check?
