[2008R2] Exchange Server 2010 - removal / fresh install
I'm running in a 2008R2 test environment and have been struggling with trying to create a fresh install of Exchange due to some configuration / authorisation issues.
I have 3 test servers. One running AD GC, one running Exchange 2010 Typical install and one running Edge Transport and Forefront TMG / Exchange Server. The two exchange servers are virtual machines using Hyper-V.
I have been using snapshots to roll back configurations to bare bone install but Exchange Server settings seems embedded in AD. Its the second time I have had this problem - last time I rebuilt the whole test network, but i'm not planning on that this time.
I tried to do a reinstall of Exchange server on a fresh Windows install, same server name, but Exchange says that the its in a incomplete state and need to use setup /m:recoverserver (or whatever it is) but that fails due to a corruption issue with the certificates - the root cause of my transport errors in the first place that I am trying to solve.
Q1: Can I delete exchange from AD and make a fresh start? There is some online documentation, but its all unsupported and for earlier versions of Windows and Exchange. So the instructions and structures mentioned are not the same.
Thinking of changing the server name to something different, I got Exchange installed, but the old server, and mailboxes etc are still listed in Exchange.
Q2: How can I delete this now defunct server and mailboxes from Exchange? Again, I have found instructions for earlier versions, but nothing matches the tools or structure in 2008R2 and Exchange 2010.
As its a test environment, nothing is precious except my AD DS/GC server that I need to keep intact.
