Might be something in that as both servers are going to be working as DC's. I really wanted all the user data and files etc. to be on one server. Ah well, will have another look on Monday when I've had a think and some eye rest. I was so looking forward to having it all done by now, hey ho the idiosyncrasies of IT technicalities are what keeps me interested (ha ha).
Since your changing it anyway I would look into using DFS to make a perssistant DFS mapping to use, this way even if you change the location again you will not need to change all of the paths once you have them pointing at the DFS link.
