We built a new upgraded Exchange 2007 org, with 2 CAS/HT servers, and a 2007 SCC 2-node mailbox cluster, with one legacy 2003 mailbox server for safety. All of which works perfectly.
Now we are ramping up production and trying to put in a second 2007 SCC 2-node mailbox but having sever problems. Both servers OS match our previous SCC cluster and show no problems there, cluster install is also functioning fine. When we tried to install the first active node in Exchange using the name of the old 2003 cluster the install failed (we think because remnants in AD didn't like reusing the name but we aren't sure).
So now we have a "corrupted" mailbox server sitting in the org that refuses to be uninstalled. We have tried gui...but that launches into "maintenence mode" that refuses to allow you to do anything. We have tried EMS using ./setup.com /Mode:Uninstall and ./setup.com /Mode:Uninstall /RemoveCMS /CMSName:"Exchange1" both fail.
How do you forceably remove an exchange server from an org?
