Rebooting a DFS Server

I'm using Software Pursuits SureSync to keep a production and standby spare file server hosting roughly 2TB of data in sync at one Customer site. I'm using it in a unidirectional capacity but I know that it supports bidirectional sync (and delta compression, and using the NTFS change journal, and a host of other features). There is an add-on lock manager available that, I would suspect you might also need. I've been very happy with the software (we've been using it for roughly 6 years) and, with a couple of issues that the manufacturer addressed, it has been very stable and reliable.

Have you seen this DFS Server Prioritization document? It sounds like even if both of your servers are in the same "site", you can still set a different "target priority" (according to that document). It sounds like this should prioritize the servers as you would expect from a client point of view.
