Outlook not finding Exchange Server

We have an Exchange Server system with Exchange 2000 running on Windows
Server 2000.

About 4 or 5 of our Outlook 2002 installations suddenly have stopped finding
the Exchange server.

The other 300 or so are doing fine.

I have repaired Windows XP, reinstalled the Service Pack 1, reinstalled
Office XP, Installed Office 2003, wiped out profiles and recreated them -
nothing seems to reconnect these installations to the Exchange Server.

I did finally get a ubiquidous error message on the machine that I installed
Office 2003 on. It says "A system component, RPC, required by Outlook to
connect to the e-mail server is not configured properly." So how do I
configure the 'Remote Proceedure Call'.

If I reformat and reinstall the problem goes away, but I'd like to find a
fix, not just work around it.
 
Verify that you have the following registry keys.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Rpc\ClientProtocols]
"ncacn_np"="rpcrt4.dll"
"ncacn_ip_tcp"="rpcrt4.dll"
"ncadg_ip_udp"="rpcrt4.dll"
"ncacn_http"="rpcrt4.dll"

I found Knowledge base article 325930 which suggested just what you
mentioned. One of the computers had only one of the Client Protocols, the
other didn't even have the Key ClientProtocols listed. adding them fixed the
problem.

Thanks
