From an entry on Dan Petri's forums:

I would suggest you start by removing RPC over HTTPS proxy from add/remove programs, then removing the two RPC virtual directories from IIS Manager. Run IISRESET to write the change to the metabase. Reinstall the RPC over HTTPS proxy and do the registry settings again, on both the Exchange server and the domain controller.

Test again.

There are only three things that go wrong with RPC over HTTPS on Exchange 2003.
1. Certificate problems - not trusted, name mismatch etc.
2. Authentication issues - the virtual directory is set for basic and the client for NTLM (Integrated) or vice versa.
3. Registry settings are wrong.

Although I've also seen firewall issues too - so it is a good idea to use fixed ports.

There's a step-by-step article on how to configure everything here:
