I am running Exchange server 5.5 SP4 on NT Server 4.0 SP 5. I am trying to change the NIC card but when I install the new card and boot the server my workstations cannot connect to Exchange. All other networking works, Shares, network printing. If I put the old NIC back in Exchange works like a charm. Any help would be appreciated.

Just out of curiosity, if your old NIC works, why are you changing it?

By the way, your problem isn't an Exchange issue, it's a connectivity issue. Sounds like maybe your IP settings changed. Go back and check

Are there any errors in the application and system logs? Do the exchange services start?
Can you ping the exchange server by name and IP?

If you can ping by ip and not name, install dns or put a file called hosts in the c:\winnt\system32\drivers\etc for NT, c:\windows for 9x.

Hosts(no extension) file should include this one line.

192.168.0.2 exchangeserver

instead of 192.168.0.2, put in your exchange server address, and instead of exchangeserver put your server name.
