Windows 2003 - Firewall Disabled due to NAT

By anandsand ·

I have a Windows 2003 ENT server with SP1., this is my ADC in the Domain. Somehow, the NAT service was started on the this systems and I am not able to ping the system from my N/W. When I try to open the windows firewall I receive the message "Windows Firewall cannot run because another program or service is running that might use the network address translation component (Ipnat.sys)".

Kindly advise me how to fix it?

Thanks in advance.
