Pinging

[Andre Moshier]

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 this
that I believe is the issue. If I ping my exchange server
by it's name it trys to ping the old IP address of the
exchange server. 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.

Just work through the name resolution process.

What do you see if you 'ping servername'?

pinging servername with 32 bytes...
or
pinging servername.yourdomain.com with 32 bytes...

The difference determines which name resolution mechanism is being used.
( DNS or NetBIOS. )

Here's a few more tests:

Go to a command prompt, and do:
ipconfig /flushdns
Then:
ipconfig /showdns

Does the machine name appear? If so -> HOSTS file problem.
Go look in the hosts file with a large machete.
Chop out any entries relating to the server.
Then try again.

Now, try DNS.

nslookup servername.yourdomain.com

Bad IP? -> Check which DNS server is doling up the
bad IP and go hit it with a stick.

OK so far?

Check NetBIOS namespace....

Go to a command prompt, and try:

nbtstat -R
nbtstat -c

does the list contain the bad IP?
-> LMHOSTS file problem.
Go look in the hosts file with a large machete.
Chop out any entries relating to the server.

net view \\servername
nbtstat -c

does the list contain the bad IP?
-> WINS server doling up bad IP.
Go hit it with a stick.

I have experienced the same problem and it was easily
resolved by adding the IP Address and Exchange Server Name
in the Hosts file. Worked like a champ!
