We use the following Location-Department-Asset Tag For location and department fields we use a two to three letter abbreviation. So a Customer Service desktop with the asset tag of LKI13 would be: DEN-CS-LKI13 For laptops we substitute LT for the department so: LA-LT-LK9F7

What I've done in a situation like this is configure two Netsh batch scripts. The first configures the NIC for office use. The second configures the NIC to use DHCP and Level 3's public DNS Servers, 4.2.2.1 and 4.2.2.2.
