Use symbolic names to configure services. pop CNAME machinea.x.y. then change it to pop CNAME machineb.x.y. It's a bit late for that advice, but better late than never. Sooner or later you'll have to get those users to reconfigure, and if you have them use a symbolic name going forward, you will only need to do it once. You can tunnel POP from machinea to machineb with something like Pete DaSilva's plugdaemon, but that just postpones the inevitable, and it's going to be an awful lot of tunnels for 13000 users. <http://www.taronga.com/plugdaemon/> if you want to try it. -- Clifton -- Clifton Royston -- LavaNet Systems Architect -- [EMAIL PROTECTED] "What do we need to make our world come alive?
