Netware 5.0 and Jet Admin

I am installing Netware 5.0 on a new Dell PowerEdge 4300 server. I can not get the HP jet admin cards in the printers to find the file server. I used Jet Admin 2.5 to set up the jet admin cards and rechecked all que names and print server names to make sure they are correct. The 4 jet admin cards worked fine on my old Compaq server using Novel 4.11. What am I doing wrong?
