network browsing in 9.3 KDE

I have two 9.3 systems that you cannot browse the network in, using KDE (updated to 3.4) Neither of them will find my server's nfs share and let the user mount it, though fstab has the info and will mount it from Gnome. Gnome is on one machine only. How can I resolve the network browsing problem, and the user finding the share to mount? Mike
