I get the following error message when i try to setup outlook with an
exchange server account;

"The action could not be completed. The connection to the Microsoft Exchange
Server is unavailable. Outlook must be online or connected to complete this
action."

I have a Small Business Server 2003 setup on our local network with around
17 or more client computers. The Computers are either windows 2000 or XP
running outlook 2000 / 2003. All computers have successfully connected to
the exchange server except one.

The problem computer is runnning windows xp pro with outlook 2003 installed
I have tested the following: -

1) uninstalling / reinstalling outlook
2) disabling & removing any firewall software
3) deleting & recreating a new outlook profile
4) i can ping the servers ip address, resolve dns, surf the web, etc
5) i have been able to connect to the mailbox using a different computer

You are most likely missing some registry keys that deal with RPC
connectivity. The prefered method to correct is to uninstall/reinstall the
networking bits (e.g. remove/add tcp/ip should be enough). However, check
to see if you are missing any of these values.

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