Is the computer in question on the domain? Have you tried changing it to NTLM Authentication?
Verify the IIS VD's have the correct permissions: (I think these are correct) Exchange - Integrated and Basic only Public - Integrated and Basic only RPC - Integrated and Basic only ExchWeb - Anonymous, Integrated and Basic ExAdmin - Integrated and Basic only Make sure SSL is enabled on all except ExAdmin. If it still doesn't work, use the rpccfg /hd command to verify the ports are correct. Jay Dale I.T.

What does outlook /rpcdiag say? Almost all the time when this happens it has either to do with permissions on the virtual directories in IIS or with the ports in the registry. Jay Dale I.T.

From: Clayton Doige [mailto:clayton.do...@gmail.com<mailto:clayton.do...@gmail.com>] Sent: Wednesday, April 21, 2010 9:35 AM To: MS-Exchange Admin Issues Subject: RPC/HTTP Revisited The other day I posted a question regarding rpc/http in an Exchange 2003 environment where the FE nlb cluster Exchange is sitting in a DMZ - turned out that Checkpoint was overriding some of the allow rules with it's smart defense stuff. Have a different problem now. I am on the local network with a fully patched Windows XP virtual machine, and a fully patched installation of Outlook 2003. If I set up a standard user profile and configure it without rpc/http no problems, as soon as I add the exchange proxy settings for rpc Outlook just continually prompts for a password, and goes no further (I am not asking Outlook to remember my password here - I want to have it accept it when I put it in) Any tips on what I am doing wrong here would be greatly appreciated.
