Login Hook with Network Home Directories

I am running leopard server 10.5.3 and manage a bunch of macs setup with network home directories. The first time a user logs in I would like to be able to run a login hook that will move certain files and folders in to their home directory from a local directory. For example, one of these folders is the Microsoft Office User Data Folder. My problem is that I cannot figure out how to have the script access the network directories. I have tried using the server mount path "Network/Servers/server.example.com/Volumes/Data/Users/" however this has not worked, either because it has not mounted at the time of the scripts execution or because the local root user that executes the script does not have permission to access it. Thanks in advance for the help, it would be much appreciated. -Sam
