IP addresses - DNS/DHCP question
Posted on 2012-08-22
We have a small office with about 50 Windows XP computers and a Windows 2003 Server running Active Directory, DNS, and DHCP. Occasionally, I will notice that one of the XP machines has a different IP address compared to what the other computers "think" it should be. For example, someone was trying to use remote desktop today for one of our lab computers, and when they remote desktop'd to the computer name, it couldn't connect. It turns out the computer trying to connect to it thought the IP address was 192.168.2.122 but when I check the ipconfig information of the target machine, it was 192.168.2.124. How do I synchronize all the computers to the server so they all "know" the current IP addresses of all the other machines on the network? I think that if I do an ipconfig/registerdns on the machine with a different IP address (at least different than what the other client computer think it should be) that will register it's current IP address with the DNS server, right? But then how do I get all the other computers up to date with the DNS server/real IP address assignments?
