Managed Login Scripts & Workgroup Manager

Hey all, I am trying toimplement Managed login scripts on a machine group which consists of just one test machine at the moment, & all I seem to have is problems. After over coming the "is not a CFArray" error I got in my system log I not get my script returning 1 in the system log. The script is very simple, it creates a symbolic link to a partition on a hard dxrive that the users cal use as a scratch disk. the script is as follows #!/bin/sh ln -s "/volumes/mac HD" "~/Desktop" it's litrally that simple it will be more complex but firstly I need to get it to work. If anyone can shed some light on why it returns one that would be brilliant. I'll post a copy of the log if anyone needs/wants to see. Thanks Dave Maltby
