Lots of possibilities here.
First, are the Win9x computers getting a valid IP address from the DHCP
server, or are they getting a private range (192.168.xxx.xxx) address?
Second, are the Win9x computers getting an IP address in the same range as
the 2000 and XP computers?
Third, can the 9x systems ping the DHCP server and the PDC by name and by IP
address?
Finally do they all have something in common other than all being 9x
clients? Are they perhaps all on the same switch or router? Can you swap a
9x box and a 2K/XP box to see if the 9x box works in a different location?
