I'm using Windows Server 2003 along with MS's DHCP server. We're making some changes in our environment that we'd like to phase in - these changes will require a different default route, perhaps different DNS servers. All of our clients are Windows - 2000, XP, Vista.
We'd like to find a way to say "these machines will get THIS default route/DNS, and that set of machines will get another set."
The DHCP "User Class" feature would seem to be a way to handle this, but I can't find anything about how to centrally assign the "User Class" for a given machine centrally. Everything I've found refers to issuing an ipconfig command on a given machine to change the user class. Is there a different way?
I suppose that I could arrange it that machines in particular group run a script which issues that command - but is it persistent across boots? The script wouldn't be run until the machine has a DHCP address and connects to the domain, so would it work for the next boot/DHCP renewal?
