Uninstall and reinstall tcp/ip on the rogue computer. I had the same problem once and that fixed it.

I have 140 Mailbox enabled user on the Exchange 2000 server and all client Outlook works fine. Only 1 (but the client of the big BOSS ... ach !) client doesn?t start. I install the Microsoft Exchange Server service in the client, I type the server name and the mailbox name but when I try to check the connection the response is ?Unable to connect to the server?. If I change the username the results is the same. If I change computer and type the same username all goes right. Note that the computer browse the network correctly, open shared folder on the exchange server and so on .... Have you any ideas ?
