RPC over HTTP

I have an Outlook 2003 client that is connecting to exchange server via RPC
over HTTP. Whenever Oultook is launched or an active sync is attempted with
the client, the user is prompted to enter a username and password. Is there
a way to turn this authentication off? Other systems on the network
configured for RPC over HTTP access are not prompting for authentication.
I'm puzzled by what is causing this.

Thanks,
Mike
 
Do you have the authentication set to Simple or NTLM?

The Proxy Authentication (under Exchange Proxy Settings) is set to Basic.
The Logon/Network Secutity (security tab) is set to Kerberos/NTLM Password
Authentication.

Bump.
I never heard anything on this. Is there a way to turn off the
authentication on RPC over HTTP?

Thanks much,

Just FYI...
Unchecking "On fast networks, connect using HTTP first, then connect using
TCP/IP" and "On slow networks, connect using HTTP..." seems to have resolved
my issue.
