Hi ...
I am using TMG 2010 SP1 as Edge FW on Win Server 2008 R2 having 02 NICs. The problem is that my TMG server providing internet services properly without any problem and delay, but when i ping and RDP my TMG it respond only for 40-50 seconds and after this time connection time out for ping requests and connection lost for RDP. also Ms outlook didn't send or receive email after 40-50 secs. When i restart my server it again start responding for 40-50 seconds only for once.
1. I have configured System policy editor to allow ping and RDP and created firewall rules to allow both protocols and same for MS outlook.
2. I have verified that both of NICs of TMG (Broadcom) are working properly and NICs Driver Ver. is 5.2.05
3. My TMG can ping all the clients and DNS, DC server.
4. there is no updates KB2888049, KB2882822 and KB2913431 are installed on my Win Server 2008 R2 as i have read blogs about these updates are creating issues like that.
If any body have an idea about this mystry issue please help.
