I have an XP Professional laptop. When at the office I login and authenticate against a domain controller. When physically detached from the network, I still have the ability to tell my computer to login to the domain via caching. The problem is that when the computer is physically detached from the domain, and I login to the laptop, if ANY network interface is enabled and DNS addresses are assigned to a NIC, the computer sends CONSTANT DNS queries looking for the domain controller. The problem is that the system literally "halts" after every DNS query, waiting for the domain controller to repsond. Obviously since I am off the network the DC never responds, but the computer is useless while it waits for the DNS query, or lack thereof. Even if I do something as simple as click on the Start Menu, or double click a folder shortcut on my desktop that does not reference a network at all, DNS queries are made, and they must time out before I can proceed. Its like this computer is married to the DC and is always looking for it. Any ideas?
