Mr Moose,
We're loosing you... If you really want to do the SU thingy, you need to factor two permissions.
1. The permissions to the local reg.
2. The permissions to the source files on the network.
If you have one but not the other, you have nothing.

I suggested two alternatives, Task Scheduler or remote reg mods.
Task scheduler is similar to SU without the risk of password ripping. You assign a task with Jens' ScheduleTask() UDF using an account with admin rights to the local reg and enough network rights to the source files.

Of couse you could copy the source files local for either SU or TaskScheduler.

The other option (remote reg mods) would require that you translate all the reg keys and values into KiX and then do all the mods from within KiX and not through a RegEdit merge.

Lonkero's suggestion of using WaitFor is one that I've been kicking around for some time. Haven't seen CJ do anything with it... I first saw an implementation by Wimmo... used to install SUSS, I believe. WaitFor would allow you to 'serialize' the task. That is, to hold the logon (client) script while the admin (server) script did its thing.
