A few years back, I remember having to do something similar. Bear with me as I try to remember:

1. There should be a directory \\[server]\Clients\Response\[computer name of user]. Make sure the new computer name is present, if not make one.
2. Copy files from another computer name to the new computer name directory.
3. Change the settings in the Netparam.ini file in the directory you just created to reflect the new user. This file should be self explanitory as what to change.

I hope this helps but I might be wrong. Oh ya, don't forget to add the actual user account and bla bla bla, you know the rest.
