Why you use IPs on the client instead of names? Here we resolve everything by 
Wins/DNS. So no need for using IPs.

You mean the name of the server or from the shares?
If you keep the IP you can also name the new server as the old one (what I 
would suggest). And if the shares also keep their names, nothing changes out 
of client sight.

How are the shares connected? If you use a logon script, you can change this.
Just disconnect all old shares before you map it. And if the shares are mapped 
with "/PERSISTENT:NO", they are automatically disconnected after logoff.

And don't forget to set the domain SID of the new server to the one of your 
old server. Otherwise your clients doesn't accept the new server as PDC for 
the domain, even if the domain name is the same.
