Question : ISA/TMG issue

Hi experts

Sometimes my TMG server begin blocking different protocols. I get 0x80074e24 FWX_E_CONNECTION_KILLED in log. I have attached a screenshot from the log.

The problem seems to be solved by restarting the server.

I have seen these with DNS, RPC, LDAP, SMTP and other protocols. I recently replaced ISA 2006 with TMG. I never saw this problem when we used ISA 2006. Anyone knows what causing this - and if it can be solved without having to restart the server?

Thx

Answer : ISA/TMG issue

Can you check monitoring, if the IP that this is coming is being blocked due to flood mitigation?
