Our TMG 2010 server is set up in a test situation and is currently only used for outbound Internet access, no inbound connections yet pointing to this route. We have been struggling with the issue that users using this outbound route will loose internet connectivity and we cannot pinpoit the reason. Only restarting the server will fix it, temporarily.
We have been struggling with this issue for a very long time now, we tried clean installs and a MS TMG specialized partner looked at the installation and deemed it best practise. The only thing he could think of was that HP's teaming software for the LAN connection could be the culprit. He changed it to Network Fault Tolerance instead of Transmit Load Balancing. That did not help either.
The server doesn't show any errors we can work with. only users loosing their internet connectivity.
Any idea's how to solve this situation? Other option is to pack in this TMG and go for an appliance.
TIA,
Fred
