I'm currently running kixtart for my login script. We have 200 servers on the network in 180 locations. Every location is connected via a frame relay connection.
On every location there is a BDC (Single Domain Model).

In Usermanager i've configured A homedirectory for every user, the homedirectory is on the nearest server. I want to make sure that is is not possible for a user to logon to the network if he is not on his own location.

I want to make a check in my login script to see if the DHCP server is the same as de Homeserver. I don't want to use de logonserver because I happens sometimes that a user is logged on via another location.
