Pinging the wrong IP address

A

Andre

About a two weeks go we changed our IP addresses within
our company. I have one workstation that will not connect
to the exchange server through outlook. I have found that
if I ping my exchange server by it's name it trys to ping
the old IP address of the exchange server 12.xxx.xxx.142
and the address should be 192.xxx.xxx.4 This is the only
workstation it does it to, why and how can I change what
IP address it is looking when I use the name of the server
vs the direct IP address.

No host file configured? If not, try ipconfig /flushdns from command prompt.

Have you restarted the PC? It's hard to imagine that you haven't in two
weeks, but it does have a cache which remembers IP addresses for host names.
You can use IPCONFIG /FLUSHDNS to clear the cache.

If after that, it still does it, I'd wonder if there is a possibility that
it was hardcoded in the lmhosts file. Do a search on the PC and look for
it. It's a text file that can be edited. See if there is a reference to
the hostname of your exchange server for some unknown reason. This may have
been done as a troubleshooting step long ago..and never removed. On a side
note, you can make an entry into this file to "patch" your problem if you
don't feel like working too hard on this.

After that, I'd be curious what DNS server it's looking at. It has to be
getting the IP address from somewhere. It's not making it up. Check to see
that it is using the DNS server that you think it should be using. Though,
I don't imagine you have miscellaneous DNS servers sitting around your
office. Which...brings to mind another question. Are you using a DNS
server in-house? It makes things work much easier since Windows 2000. Are
you using WINS?

What operating systems are we talking about here....both server and
workstation?
