I have a new 2003 single server exchange install. I am having no luck with RPC over https.
The server is installed in a the site domain with a seperater domain controller in each site.
the site with exchange has
mx1.domain.local - exhcange server
dc2.domain.local - domain controller (dns)
I have followed a heap of guides the only one that talks of RPC in a single exchange server - with a seperate dc.
In particular he mentions including the dc in the Validports entry
In IIS I have set the rpc directory security - authentication to basic and the default domain to domain.local
Anyway now to the problem
When I test the server in a browser on the LAN or the wan eg https://mx1/rpc
I get a prompt for a username and password however authentication is unsuccsessfull after three attempts I recieve a "HTTP Error 401.3"
I have tried a world of username password combinations with no luck.
owa is working fine externally.
Any ideas welcome.
