Automatic Users Mail Profile

Using newprof and profgen I'm trying to get a logon script to create an Exchange profile on W2k and NT4 workstations. The profile is created but the services within are not. I've got sample scripts which others say work - but not for me. I simply want a profile to be created using the users logon name and the server "mail-srv1" to be added along with a Outlook Address Book.
Here are the important bits;
