I am running Windows 2000 server v5.0, Svc. Pack 4.

My DNS event log is filling up with Event 5504. "The DNS server encountered an invalid domain name in a packet from The packet is rejected. " I have seen some sites recommending that I turn off my DNS forwarding service. How do I do this and is it even advisable? If not what should I do?

5504's are based on an illegal character. No undrescores, spaces, etc are
allowed. You'll have to find the offending machine that has that IP and
rename it.
