Recently purchased Latitude 600 model laptops.  The laptops have integrated broadcom nic cards.  Using Novell client 4.83 and have tried 4.9.  Also undated the bios from A05 to A08.  Still not logging into network.  Network guys have sniffed and see the IPX traffic coming in and leaving, but it appears to be leaving before it is accepted.

This is also happening on desktops with the same type Broadcom integrated NICs.  Installed a intel card and everything worked.
