I have a single Exchange 2003 SP2 server with one Outlook client connecting via RPC over HTTP. After working for several weeks without a hitch it stopped working - The Outlook client cannot connect. Nothing has changed on my firewall and I did not modify anything in the Exchange server during the period in which it failed. There are no obvious errors in the system logs.
In the document I used to set up RPC over HTTP with a single Exchange server (no back-end/front-end stuff), it tells you to test it by going to http://your.server's.FQDN/rpc
, authenticating with "domain\username." You are supposed to get an error that says "This page cannot be displayed. HTTP Error 403.2 - Forbidden: Read access is denied" as a confirmation that RPC is working, but instead it keeps asking me for my username and password. I went back through the entire document to verify that all the setting are still as they had been configured and they are.
Any guidance on how to troubleshoot this would be appreciated.
