How do I change IP addresses within Active Directory?

Expert Laura E. Hunter explains to a reader how easy it can be to change IP addresses in Active Directory.

I need to change our IP address range.

I have a DC running Windows Server 2003 with Active Directory, DNS, DCHP and Exchange Server. Is there any possible...

way that I can change my IP address range to a new one. What would be the consequences?

You can easily change the IP address of any server or computer within Active Directory. To ensure that services like Exchange continue to function, ensure that your DNS records are updated in a timely manner, and update any server's site affiliation in Active Directory Sites and Services. If you have client computers that rely on a re-IP'ed server for DNS resolution, be sure to update the TCP/IP configuration on the client side as appropriate.
