I have setup RPC over HTTP on 3 servers now. All of them were stand alone servers as in NON small business servers. I am working with a SBS 2003 server. It's a brand new install, everything has been patched up to current levels. SBS 2003 Service Pack 1, Exchange 2003 Service pack 2.
I have configured the server in System Manager for Exchange to be a back end RPC server. The problem that I am running into is when I try to check the http://mail.mydomain.com/rpc I am getting a prompt for creating a .NET Passport account. If I test the same link inside of the network http://server/rpc
I am prompted for a user name/pass. I checked the RPC virtual directory in IIS just to see what it's set at. Under directory security the only option checked is .NET Passport authentication. I know that server setup vary from stand alone server to small business server, but this is driving me crazy. If I look on another server I have setup RPC over HTTP and it's working correctly. The directory security shows something totally different. The only 2 options checked are "allow anonymous" and "intergrated".
Anyone out there have some ideas?
