SQL 2012 Peer to Peer question

Hey guys

One more question about Peer to Peer.  Lets say I have 6 nodes scattered around the country and they are all communicating via VPN and are working great.  If one of them goes down, then the people in that area would be automatically switched to another server... thats the easy part.  Now, the hard part is recreating that node.  The node creation process requires that the server that its coming from or will initially connect to be inaccessible by other people.  If we have backups of the nodes running and do a restore from one of those backups and get the server back online, will it automatically start publishing and subscribing and will there be any problems?  I am guessing that UNTIL its fully synced that I should make sure that no one logs into it and makes any data changes right?  Will it sync automatically if it has been down for a few days?

Thanks!!

So I have less than that certain time frame to rebuild the server or I have to go thru the wizard again to make a node.  Wizard requires using the original source and not allowing any access to it during the build.

Ah. Thanks. I was just thinking though that if the data center can't get me new hardware in 72 hours then I shouldn't be there anyways. :-)
