I'm about to install active directory on a W2K3 server.
It is configured with a certain IP address, Mask and gateway.
If i change all this paramaters (move to an office in a different city)

My question is how will there be any problems changing the IP settings after
the AD install?
The server will have DNS zones (which are not configured yet) so i don't
think that will a problem.
Basically what i want to know is what potential problems can i expect after
changing the IP settings?

Is DNS also hosted on the DC?  If so be careful to change the DNS settings in TCP/IP to match the DC's new IP address.


Check out this from MS:

The DNS will be hosted on the DC. It's not configured yet but i know that
while installing the AD it does some DNS configuration by default.

I've done this lots.  I'll build a DC on production, then bring it into the lab that is in a different subnet and all I do is pretty much what's in that article from MS.  Just change IP and repoint the TCP/IP dns back to itself and then power down and move the machine.  It's all fixed when I power it back up.

You can even try this before you ship it out.  If you have another local subnet try moving into that subnet and see what happens.

If you do have issues it will be DNS.  Most likely the host A record.  Just make sure you don't have two of them (i.e. the old IP and tne New).
