I'm currently at one of our branch sites trying to get RPC over HTTP
to work on an Outlook 2003 client and haven't had any success.
As far as I'm aware I'm using exactly the same settings on the
client that I'm using on my own laptop. My laptop is connecting fine using RPC
over HTTP, but other clients at the remote site are not.

Mutually authenticate is ticked, with the following entry below it:
msstd:external FQDN of OWA site.
Basic Authentication is selected in the bottom drop down box.
At the remote site, when I run outlook /rpcdiag I get the no real output, just:
Server Name Type Conn Status
---- Directory --- Connecting
InternalExchangeSrvName Referral --- Connecting
..these two entries then disappear, then I get a popup saying "Your Microsoft Exchange server is
