Hello,
Yesterday we decided to upgrade our TMG servers to service pack 2 as they were still on the orginal release.
We have an EMS server and 2 TMG servers in an array. The upgrade to the EMS seemingly went well however when we ran the SP2 upgrade on the first TMG server we starting seeing the following error -
Forefront TMG cannot determine array member's status. Therefore, any attempts to establish VPN site to site tunnels may not succeed. Forefront TMG will check array member's status periodically. When the array member's status can be determined, tunnels will be established, as necessary.
All looked ok in the management console which showed the configuration is apparently up to date and the server had a green tick.
However, on looking at the logs the server is not accepting any connections and all traffic is being blocked under the default rule.
We've disabled NLB for now so all connections are going via the other array member however I am baffeled as to what has happend.
Anyone seen this before?
Many Thanks,
Chris
