Just a quickie, is it safe to reconnect an old 2003 DC back on to the network?
The hardware died a couple of weeks ago and we’ve just got around to trying to sort it out. It’s now running again although temporarily, my plan was to bring it back online and take it out of the domain cleanly.
There are other DCs running and the domain is 2003 native. It did not hold any FSMO roles.
