windows 2000 machines cant see samba

[Alex Snow]

Hi all. I have two different versions of windows running on my networked 
pc's. the older ones that cant handle anything newer are running win 98 
se. These machines can see the shares I have on my linux box fine and I 
can mount shares on them from linux. On the faster machines I have 
win2k. This cant see the samba machines nor can the linux box see them. 
Does anyone have any ideas why this happens? all the machines are 
connected to the same lan.
I'm running samba 2.2.8 slackware 9.1.
