PCs with multiple network cards

Greetings,

Almost all of my users are on laptops with built in wireless.

I am running in a Windows 2003 Active Directory environment.

My problem is when my users move around the corporate campus. They get assigned multiple IP addresses.

If we try to connect to them via their FQDN, it often points to an IP address that they aren’t currently using. Sometimes another user will have already been leased that IP address and so the IP address and the FQDN aren’t correctly matched.

Are my DNS setting wrong? Has anyone else dealt with this issue?
