It's interesting how we get details late in the thread that invalidates everything we've suggested. Chris is right, that IPCONFIG would only work on NT.
I agree with Jens. Run KiX from \NetLogon and do all the checks from there. Nothing need be installed on the workstation at that point.
Even if you did install KiX on a process machine, what would that matter? Unless they use KiX for other than logon scripts it wouldn't hurt. I mean, it's just one or two files.
