I've been watching DNS forwarding take place with a packet sniffer. When
doing so, the reason that forwarding is failing is quite obvious: all of the
forwarding traffic is sent out with the _old_ IP address. This is an IP
address that isn't associated with any NIC card. It's an IP address that no
longer exists on my system to the best of my knowledge.

I went into the DNS Manager and added a new server with the _new_ IP
address. I deleted the old server (which had a name, but no IP address).
No change.

I went into the DNS Manager and specified the IP addresses of the two NIC
cards on the server as DNS Server IP addresses. No change.

Can anyone shed some light on where the DNS Manager is picking up this old
IP address? I can't find it anywhere in my system. I've done some registry
searching.

Probably WINS or an lmhosts or hosts file. What happens when you ping the
name? does it return this 'old' ip?

Pardon my ignorance/naivete:
Ping which name? mydomain.com or ns1.mydomain.com or something else?
Ping from where? on my server? from the internet?

Sorry, I just don't understand what you think needs to be done and what the
expected results might be.

I know how/where to look for lmhosts and host files. How would I
investigate possible WINS interference?

Thanks,
