If I remember correctly, from server manager make your ibay on the server with relevant permissions for the users.
From a workstation run the normal setup but rathe rthan installing locally i.e c:\Line50 install it to a folder in the ibay that you have created - e.g. s:\Line50.
After that and as mentioned earlier, run netsetup.exe from the server from each client machine.
Sit back, make tea, .... or something

and relax in the knowledge that another W2k box has bitten the dust and the world is infinitesimally better off.
Job done.
Now, if I could just sort out my bloody raid

problem I'd be a happy bunny
