GPO and scripts

[downloadkid]

Morning People, need some help.....
Objective:
I work in a school that has 4 IT suites. We are running win 2K server with XP clients. As it stands the computers are all lumped together in one group, default Domain Computers.
What I would like to do is create 4 OUs one for aech suite / Location and be able to aply GPOs on each of the OUs.
Part of the reason is that I want to be able to assign a printer through the GPO to users loging on in each area. IE someone logging on in Room 1 on a room 1 machine gets linked to the room 1 printer.I have seen scripts that do this from the logon at domain level that recognise comps based on naming convention, so yes I could do it that way.
However in playing with the GPOs I am now focused on understanding why I cna't get it to work.
I have created a bat file that works fine when applied at the domain level to the 'user settings'. This ensures that anyone logging on gets access to the printer.
However if I apply it to the test OU in which I have single computer, then subsequently log on that computer it doesn't work. In the GPO created for the test OU I have applied the script to both the user and computer settings, but still doesn't work, and they are the only changes I have made.
When I run a gpupdate then a gpresult it shows that the domain level GPO and test GPO have been recognised and not filtered so I am at a loss as to why the prinetr is not being given access to.
Any help would be greatly appreciated
Many thanks

I know BT in general are now promising to raise the xDSL limit from 2meg to 8mb over the next 18 months. Physically the local exchange switching can already handle this ammount of throughput so I guess its the business model that as usual will hold everything up. Still to get rid of the radio link for a single 2 meg DSL connection will suite our needs fine at this point in time..
