Windows 2000 Print Server

I have replaced my companys NT Print Server with a new windows 2000 Print Server. I have noticed that from the clients (NT and 9x) when they are adding new network printers they can see the new print server fine, but they need to expand it to view all the print queues. Before when I was using an NT 4.0 server to house all my print queues, in the add network printers list from the clients pc, the print queues showed up in the browse list as already expanded. Why do the queues need to be expanded with the new w2k server?? A minor inconvienence for my users but I was just curious if anyone had a fix for this.
