Looks like I don't have a solution yet. Using the Group Policy works
great for the Windows clients. Problem is with the Linux clients
every time a machine gets a new lease the resolve.conf gets clobbered,
requiring the user to edit the file again to add the proper dns
suffixes.

Does anyone know a way around this? Is there a way to prevent a
Microsoft DHCP server from overwriting a Linux resolve.conf file?
