Admin client requests routed through another server?

I've implemented a new server and I have one 'administrator' who is having
problems accessing the server from his desktop.  I can access the server
from my Notes client and the Admin client without a problem.  However, this
administrator - who is actually my boss cannot access the server from both
the client and the admin client.  He gets the message 'unknown tcp/ip
host'.  He can bing the server, he can access it via the browser but cannot
access it from the client or admin client.  Strangely enough, when he
attempts to access it from the admin client he will get the message that it
is trying to access it from our registration server....

Any ideas....the little $#@%^$ is going to drive me nuts.....
