I think you can add a digital signature to the EXE to avoid the popup. Doug talks about them in his articles.

I have used the scheduler trick to avoid the UAC on a local machine, but if run from the server, windows pops up another confirmation box unrelated to UAC, saying 'open file security warning... we can't verify who created this file. are you sure you want to run this file?' Only way to cut the cr#p is to turn UAC off, and that defeats the purpose. Sometimes i wonder what those Redmondians smoke...
