rpc over http

Hi,
I have used RPC over HTTP with a couple of the Vista CTPs and now Beta 2. I have also used it with Office 2003 and now Office 2007 Beta 2. In all cases, Outlook connects to the Exchange server, but continually asks me to enter my AD password. Interestingly, the first request is from the Exchange front end server, and subsequent requests either come from a domain controller or from the mailbox server. If you either move the logon dialog off the screen, or cancel it, outlook remains connected, however this times out after a (seemingly) random time and you'll need to logon again to regain connectivity ....
I know a couple of others with the same problem ... any ideas?
Thanks, Simon.
