Running a script to copy 2 files.

I’m on a network with multiple workgroups. We have a mix of 98 & w2k machines. I need to get a couple of norton files copied to all work stations for live update purposes. Problem is that I cannot find a place to have w2k machine log into primary domain, so I can run a script to copy files. I get the files to win98 boxes, but that is it. Any ideas on how to make this easier??
