Thanks to everyone who replied, I appreciate it.

I think I have a plan for Monday - I'm going to try to "keep it simple" and attempt to rewrite the mash of batch files we currently use into Kixtart - I intend to initially try a simple CASE statement to run commands based on the IP (and therefore location) of the machine.

Les - fully agree with the "teach a man to fish" principle - I appreciate the pointers.
