Changing IP addresses on Windows Servers

tmcclure
I'm relocating a Windows 2003 server farm (DC, file server, SQL server) to another building with an existing farm. I want to change the servers IP address to match the building's IP subnet. Is it as simple as changing them on the server and rebooting?

    For the file server it's no big deal at all. Change away.

    For the SQL server you shouldn't have any problems but I would test heavily to verify. Also make sure that DNS updates properly or some of you apps that point to the SQL server may get lost until the DNS servers all replicate the change.

    For the DC you want to watch out. You CAN change the IP but you will have to watch several things.
    1) DHCP- If the server delivers IPs to clients you will need to re-authorize the server or it will just stop on you.
    2) Verify that replication is working correctly between the other DCs.
    3) Make sure that DNS has all of the correct information. With DCs you can have problem in the MCDCS area.

    If you have the luxury, I would make sure that there is another DC that has the Global catalog installed on it. I might also go so far as to mmove the FSMO roles to another box durign this move if this server holds any of them. Just as a precaution.

    Best of luck.
