OK, so I got to doing a reinstall on our cursed cluster node. Well, I started with research. Good thing too.

Turns out in order to reinstall a cluster node, you have to uninstall replication. I didn't install replication in the first place, the previous DBA did. Of course, we aren't using replication….but that's a whole other post. At any rate, I wasn't in the mood to take everything down to improve our uptime (heh), especially when we're moving real soon now.
