We have weird situation with Windows 2008R2 and TMG 2010 installed. It happened two times already on 2nd Tuesday of the month that Windows dropped all connections (VPNs, routing etc) and when trying to log in remotely / locally to it you could only see welcome screen and it never logs you in (I have even waited 30 minutes). Only hard reset is an option then (it's a virtual machine running on Hyper-V R2). We tracked it down to possible `Windows Update problem... we always had option Download new updates and let me decide what to do with them turned on` which seems to be the cause of hangs. There's nothing in Application / System logs concerning the hang and in WindowsUpdate log there's: 2011-06-07 16:55:04:976 824 11f0 Agent WARNING: WU client failed Searching for update with error 0x80072ee2 2011-06-07 16:55:04:992 2904 67c COMAPI >>-- RESUMED -- COMAPI: Search [ClientId = Forefront TMG] 2011-06-07 16:55:04:992 2904 67c COMAPI - Updates found = 0 2011-06-07 16:55:04:992 2904 67c COMAPI - WARNING: Exit code = 0x00000000, Result code = 0x80072EE2 2011-06-07 16:55:04:992 2904 67c COMAPI --------- 2011-06-07 16:55:04:992 2904 67c COMAPI -- END -- COMAPI: Search [ClientId = Forefront TMG] 2011-06-07 16:55:04:992 2904 67c COMAPI ------------- 2011-06-07 16:55:04:992 2904 ba8 COMAPI WARNING: Operation failed due to earlier error, hr=80072EE2 2011-06-07 16:55:04:992 2904 ba8 COMAPI FATAL: Unable to complete asynchronous search.

The problem isn't related to manually using Windows Updates and having trouble in installing them. It's something that happens in the background and causes Windows to hang totally which seems to be critical issue for server which is supposed to be Router in next few weeks (it's in testing phase).My little website www.pro-solutions.pl with some simple/small projects.

It seems the problem is related to Time Difference between AD and TMG. Whenever the AD clock and TMG clock differs for 5 minutes (Kerberos setting can be changed to allow more time difference) it makes TMG unresponsive. Took us some time and "hangs" to figure it out!
