Workstation import at school

[ZawadaZSE]

Hi

I've got some problem with school lab. We've got NetWare 6.5 sp5 installed with ZenWorks 6.5 and I can't force workstations to create them selves in to a tree. I've created policy and configured "Workstation Import" but it still doesn't work. I don't know what to do now. On workstation I've got installed Windows XP, Novell Client 4.91 sp5 and ZfDAgent. Also I don't know how add new drivers for network card to pxe image. Does somebody know?

Thanks for help.
