From the Windows User Manager GUI (on NT)

Right. Looks like 18 is hardwired in cron.
So after you create that user and update the /etc/passwd file you would need to edit 
/etc/password and change the uid of the user to 18. With a little bit of luck
the setuid(18) will be a noop. 
Try keeping the SYSTEM uid to 18, too, for now. It's probably hardwired too. 
My head is spinning and I don't have the time to sort through all the implications.

Can you do that? Normally the network doesn't trust the local system.

Good questions.
