OK, How badly can you screw up a new server installation?
I have an existing SBS 2011 domain with a failing server (electrical failure from lightning strike). I have purchased and installed a new server (2012 standard) with hyperV. I configured a guest 2012 os for use as a DC, added the new DC to the existing Domain, and promoted it. I moved over all of the existing shared data from the old server and recreated the shares/permissions. Just as I was about to begin the process of demoting the old server, I realised I had not applied my first (and only) snapshot, taken moments after installing the new OS. Like an idiot, I selected "delete" for the last snapshot, which in VMware causes the disk string to roll up in to the last snapshot. Here, it rolled my server back to before it was promoted. Now I have to completely rebuild the new DC, and I can't use the same name because AD already has this server name in place. Is there some miraculous way I have not discovered yet to restore this server to before I deleted the snapshot, or am I screwed?
Thanks in advance.
