  • Windows 2008 R2 with TMG hangs when windows tries to download Windows updates

    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:

    We have disabled automatic download of updates for now but would be lovely to find a solution for this.

      Why would it cause total hang thou ? It can't do anything after the error happens. You can't login to it locally from Hyper-V etc.

        possibly your network configuration on the guest has gone a bit funky.
        that would A) cause the wsus problem and B) cause the logon problem because it can't find the domain and stuff

          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 which we did in GPO latly) it makes TMG unresponsive. Took us some time and "hangs" to figure it out! We fixed AD time (which was getting changed by Hyper-V host all the time) and now it seems to be fine again. It's interesting that Kerberos with Time Difference can cause such havoc.

          Hope this helps someone else
