Change IP - now no one can see computer

Hi,

This is probably a no-brainer for most of you. But I don't have enough
hairs left to pull.

I have 2 PC's (Mine #1, other #2) in my office that are both on typical lan.
I changed the IP on #2 but #1 still thinks it has the old IP. Both #1 and
#2 have been rebooted.
There is no DNS entry for either but ping was working before. I presume
that a typical windows
lan has another type of lookup for local computers.

Question: How do I get #1 to know the new IP of #2?

Hi there --

When you changed the IP address for machine #2, did you use an address from
the same IP address range?

What OS is running on the clients?

Are you using a DNS server and a WINS server, or just a DNS server? How
many other computers are on the subnet, and are you certain that none of
the other computers are already using the IP address you assigned to
machine #2?

Check the host and lmhost files to see if you have a static IP-to-name
mapping there that is incorrect.

The answer to the problem is to just post a question to this newsgroup and
it automatically starts working.
I know, I know.. but it's working now with no change.

Anyway, as to your questions. Yes there is DNS server, no WINS server. no
hosts or lmhosts hard coded entry. Most people are using XP. #1 and #2 are
XP. The new IP address was in the same subnet. You may ask why I needed to
change it. It was because this new IP had a one to one NAT mapping that I
needed to use. Anyway, I don't like it being fixed this way because if it
happens again I won't know what to do other than wait.

Just wait a bit is probably all you had to do. Machines on Ethernet
actually communicate using the hardware (MAC) address of the NIC, not the IP
address. The client probably used an old cached entry until it timed out.
