Outlook cannot find Exchange Server

[ekreiner]

For some reason, out of the blue, I am no longer able to
connect (via dialup) to our exchange server using outlook
2000. I Can check e-mail from another computer so I know
there is nothing wrong with the e-mail or the dialup
connection. I am running Windows 2k. Also, I cannot use
the "Check Name" option. Here is the error message that
I receive:
The name could not be resolved. the microsoft exchange
address book was unable to log on to the microsoft
exchange server computer. Contact your system
administrator if the problem persists.

Any ideas?

When you are dialed in, can you ping the Exchange Server?

Start | Run | Enter cmd.exe | OK
Enter PING yourservername and hit Enter

Does it reply?
