IP Address on Server

We have recently setup an ISA Server on a Windows 2000 Server computer.  The PDC is a Windows NT 4.0 computer.  We had the ISA Server set for an IP address such as 192.168.1.201 and named the server ISA2000.  We then changed the IP address of the ISA Server to 192.168.1.30.  When I ping ISA2000 from another client, I get 192.168.1.201 instead of 192.168.1.35.

Where is the DNS server that has the mapping for the hostname ISA2000?  Wherever it is, it's now out of date since you changed the IP address of the server.  Update the DNS record for this host.
clear the history on the client.

i ran into this problem a while ago, and i cleared the history in internet explorer - that fixed my problem.

also, take jhance's advice, and make sure your DNS is up to date. and make sure that the client does not have any entries in the HOSTS file. c:\winnt\system32\drivers\etc\hosts
Don't forget to also check for LMHOSTS entries.  
if the client is a w2k box from the prompt type
ipconfig /flushdns
and then try it

Here is more on the situation.  We actually use WINS.  When I go into the WINS database, I do not see any entries listed for ISA2000.  Also, there are about 10 IP addresses leased out to ISA2000.  When I ping from the Windows 2000 computer, it is using the last leased IP address not 192.168.1.30. Thanks
Yes, but PING doesn't use WINS for name resolution.  It uses either DNS or the HOSTS file.
still, knowing that ISA is attatching to 10 IP's, there is obviously a problem with their network settings or the ISA server settings, related to DHCP.

we had this problem a while back, where my personal machine was attaching to 3 or 4 ip addresses and not letting them go. we had to manually force the DHCP server to drop all IP's from my machine, while my machine was turned off.
