Shortly after we applied the Microsoft October 2013 updates to our TMG 2010 SP2 server we started experiencing loss of connectivity on our Internet facing adapter (could not longer ping the gateway etc). A reboot would resolve the issue. The problem kept recurring so we removed a couple of the networking related updates for October (http://support.microsoft.com/kb/2888049 ) and (http://support.microsoft.com/kb/2882822 ) as a test. After these were removed the problem stopped.
We inadvertently reapplied these two updates during the November 2013 update cycle and the problem happened again. We removed the updates and everything is back to normal.
Just wondering if anyone else has applied these two updates to their TMG 2010 SP2 server and experienced any unusual issues?
Thanks
