BDC IP address change

By lee.carty@emersonprocess. ·
I need to remove the WINS service off of a BDC and install it on a new server, but I also need to take the IP address of that BDC box and give the BDC a new IP address. Would that cause any problems for the domain, or what is the best way to do this procedure?

seems to me you could just rename the old bdc then remove it from the domain. the add in the new bdc with the ip address.
did you see this article:
Microsoft Knowledge Base Article - 247913
This article explains how to replace a backup domain controller (BDC) with a new computer and give the new computer the same computer name and Internet Protocol (IP) address as the BDC you are replacing.
Change the name and IP address of the existing BDC computer:
In Control Panel, double-click Network.
On the Identification tab, click Change, type a new computer name, and then click OK.
On the Protocols tab, double-click TCP/IP Protocol. On the IP Address tab, change the IP address to a different, valid IP address.
Close the Network dialog box, and then restart the computer.
Start Server Manager, and then delete the computer account of the old BDC from the primary domain controller (PDC).
Install the new BDC, and give it the computer name that the old BDC used.
During installation, use the IP address that the old BDC used, and create a computer account in the domain for the new BDC.
To preserve share and file permissions, run the Permcopy.exe utility or the Scopy.exe utility to copy shares and files from the old BDC to the new BDC.

NOTE: You can find the Permcopy.exe and Scopy.exe utilities in the Microsoft Windows NT Server Resource Kit Supplement 2 or later.

The only thing you really need to worry about is whether the clients on your domain can find the resources they need. If you are assigning WINS server addresses through DHCP, then you are all set; all you need to do is change the scope options on your DHCP server so that it has the right address for the new WINS server. If, however, you're going to change the IP address on the new WINS server so that it matches the old one, and then give the old one a new address, you have to be sure that you do it at a time when users are not trying to access any other resources on either machine. Once you've installed WINS on the new machine, it will automatically rebuild your WINS database with the correct IP addresses for both machines.

Hope this helps!
