DNS resolution 1

[deathstar]

I have a Windows 2000 server acting as a DNS and Global Catalog server, I was asked to change all the servers and workstation's IP addresses. I was able to change all the iP addresses without any problems (Straight Forward !!) and also setup a DHCP server to fix all the clients. The problem that I'm having now is that when I ping the server name from another server I keep getting a response with the old IP address but the response is timed out. Can anyone tell me how to remove or update the DNS record (Automatically or Manually), I went into the DNS console and I changed all the "A" records but after when I ping the server by name I keep getting a response but timed out with the old IP address, but when I ping the new IP address I naturally get a reply. What I want to do is ping the server by name and get a correct reply with it's new IP address, has anyone ever had a problem like this one ??? I find this quite bizzarre!!

A few things:

You said you went to another server and pinged your DNS server, is this other server running DHCP or does it have a static IP? You would have to manually update the DNS entries on all servers with static ip's.

Be sure to check the cache on the server for out of date info. From the other server type:

ipconfig /displaydns

Is the entry for your DNS server the old IP? If so type:

ipconfig /flushdns

This will clear the DNS resolver cache.

Also one last thing, don't forget when you make changes to DHCP the clients have to reboot to get the changed information.
