After deploying Hub Transport and CAS roles successfully, I have an error when I try to install the Active Node clustered mailbox server. When the install gets to the Clustered Mailbox Server installation, the following error is displayed: "Setup cannot continue because the RPC server is unavailable. This could be due to DNS information for clustered mailbox server 'server-name' has not finished replicating. Run setup again after DNS replication has completed. You can verify that DNS replication has completed by running nslookup server-name" I have checked DNS and the records are there and replication is happening. AD is running in 2003 Native Mode. I have tried uninstalling and reinstalling several times. Any direction would be appreciated. Thanks, J

Can you post the relevant piece of the Exchange Setup log file?

I uninstalled Exchange. Deleted the clustered object from AD using ADSIEDIT Reinstalled Exchange Problem resolved.

Good to hear you nailed it Jack
