I was in the same boat as you, and I had about a half dozen comand-line utilities in my logon folder, and logon time for remote users was problematic.Then I copied the files locally to the clients to try to cut that time down. Then I got missing/deleted files, permission issues in copying the files, and issues in updating/adding new functionality, with the need to distribute new files.
Then I discovered Kixtart in the reskit (sound of heavenly trumpets)... All that other crap went away, I have kix32.exe in the users windir, and it can do THOUSANDS of times more stuff than virtually every dos utility combined.
If you want it done in a logonscript Kix will do it, and usually alot easier that in DOS, and a hundred times easier than WSH.
BTW, it is very fast, and 4.02 is supposed to be even faster determining SIDs and Group stuff.
