Publishing Outlook HTTP/RPC Problems - 14.Nov.2006 7:34:21 PM

I'm hitting a roadblock trying to set up RPC over HTTP access to exchange through my ISA 2006 Server. I've followed Tom's guide to the T (as far as I know) and have exhausted all troubleshooting tips I know of (RPCdump, RPCPing, etc...) and everything appears to me as if it is set up correctly.

After I configure the Outlook client and try to resolve the mailbox name I get the prompt to enter my network credentials. Its validates my credentials, but then says the server or mailbox name cannot be resolved.

My Exchange box is front end server and backend server. I've made all the necessary registry changes.

The only thing about my tests that stands out to me is an entry in the ISA log when I try and connect:

Failed Connection Attempt: RPC_IN_DATA

and

Failed Connection Attempt: RPC_OUT_DATA.

both these entries are logged when trying to access the

http://outlook.domain.com/rpc/rpcproxy.dll?matchstick.domain.local:6004

Are these entries normal?

Any ideas of things I might try to troubleshoot this?

Hi Bret,

The ISA logs are worthless when it comes to troubleshooting RPC/HTTP connections.

What is the actual public name and what is the common names on the certificate on the ISA Firewall's listener?

What is the actual common name bound to the RPC/HTTP Web site?

Are you forcing basic authentication on the /rpc folder?

Is the CA certificate installed on the Outlook client?

HTH,
Tom
