One single server 2003 Standard has been running for several years with no problem. Quite basic installation.
Firewall is a hardware piece directly connected to the DSL-line, so no need for software firewalls either on clients or server.
Group policy (default domain policy) restrict all firewalls to be disabled.
Our problem is that the FW on the server suddenly got active (by GP it says) and this causes a lot of connectivity problems. (see attached picture).
Is this a known problem by more of you out there? Anyway, I need help with how to solve this problem.
Thanks in advance
