Removing an old SBS Exchange Server from AD and defaults

Hi All,

A new customer had a disaster where we wound up reinstalling their SBS 2008 machine into the existing AD domain in migration mode. Things are mostly working but here is the issue:

The old server still shows up everywhere for Exchange. New users created on the new server automatically have their mailboxes set up pointing to the old, dead, server. I have to use move-mailbox to fix it each time I create a new employee.

My question(s) are: How do I set the new server as the default AND remove the other one from AD?

Here's a screenshot from Exchange Manager: SERVER-300 is the dead server.

Thanks.

If you cannot gain access to this server you will need to cleanup Exchange objects using ADSIEdit. Once you have removed the old server objects re-open the EMC and the old Exchagne objects should not be present.

Steps are below...
- Open ADSIEdit
- CN=Configuration, DC=Domain,DC=com
- CN=Services
- CN=Microsoft Exchange
- CN=Organization Name
- CN=Administrative Groups
- CN=Administrative GroupName
- CN=Servers

Remove the old Exchange object for that particular server. If you have multiple domain controllers this change may take a few minutes to replicaite. Once done open the EMC and the old server should be removed.

Will.
