Exchange 2003 RPC over HTTP in a cluster - not working

We have a situation where Outlook clients are having trouble getting to an Exchange cluster which is running RPC over HTTP. The problem is that the clients appear to be incorrectly attempting to connect to a physical nodes in the cluster for the Directory (they should be connecting to the virtual server name instead). However, they connect correctly to the virtual node for "mail" connections

So the problem is that Outlook wants to connect to the directory on the
Physical cluster node but it is not configured at the front-end to
communicate over HTTPS. Outlook should connect with the directory via the
Virtual Server!

When I hold ctrl + right click and select Connections for outlook, it shows this (excerpted):

Server Type Connection
----------- --------- -----------------
[Virtual Server Name] Mail HTTPS
[ Physical server Name] Directory TCP/IP

Has anyone out there successfully implented RPC over HTTP in a cluster, or have any ideas? By the way, we have installed SP1 on the servers.

Thanks!

what should the registry setting be, for both the front end and back end servers in the cluster?

fdorsey - this is a very old question. Unlike a forum it is not possible to "bump" questions back up the list. The only people who will see your post are those that have already participated. Instead you should post your question as a new question in the Exchange Server Zone which will allow other experts the chance to see the question and respond.
