Windows Server 2012 WSUS failing error 0x800b0001. Applied update KB2720211 as per http://social.technet.microsoft.com/Forums/en-US/winserverwsus/thread/72f5195a-4c2b-4719-85d7-a8265eaba268/ still fails.
The patch on this site seems not installed: http://blogs.technet.com/b/sus/archive/2012/06/20/wsus-kb272011-common-issues-encountered-and-how-to-fix-them.aspx
Any ideas?
