I wanted to do this with some files onto the hard drive of every computer (it was a screen saver advertising the upcoming Oliver production at the school). I was able to copy the file and configure the screen saver.

I have used a script that copied the files at login.

This could be adapted to copy the file to the users home directory without too much problem.

Use the @USERID in the command like this:

copy source \\masternt\@USERID\filename

This should work fine.
