http://support.microsoft.com/default.aspx?scid=kb;en-us;326271 Marcel, Download the article in the above link, and refer to the section, "Configure a Clustered Back-End Server" This document is for Exchange 2000, but applies to Exchange 2003 as well with very minor differences. When you have clustered back-end Exchange, there are some additional steps necessary to get to work. The above document provides all necessary steps. Thanks. HTH.

The cluster itself is working fine and so is the exchange installation on it. Our domain already has a single exchange server in the network that currently Holds all the in use mailstores. Now for unclear reasons i cannot get OWA to work on the cluster. Could this be because the single server is currently running OWA (they are in the same domain and see each other) and if i stop the webservice on that machine will i be able to get it working on the cluster or is there some other reason for this? IIS is running and when i connect to port 80 i get a loginprompt, when i log in i get a 500 internal server error. I also installed a certificate for SSL but it refuses to use it. I would like to have OWA running on both machines for the duration of the test before the migration of the single machine to the cluster. Thanks for any help in this!
