Why do some networked computers show up but others don't in network discovery on windows 7?

Hi There,

I have a windows 2003 server with domain setup and I mostly windows 7 pcs connected to it.  For some reason about a month ago I would go to my network list of computers and instead of showing all 12 systems plus the server all I can see are 6 of them and no server.  Whats odd is i can still access the server no problem but network discovery isn't showing them.  Does anyone know why this is and what i can do to fix it?  I have already tried to turn off network discovery and turn it back on.  I have tried to reboot my pc and the server.  I am next going to try to reboot the network switches.  Is there something in windows itself that isn't letting me detect all system and my server?  Can i refresh this list?  I have antivirus disabled and firewall as well just to eliminate that as a potential issue.  

Thank you

I had this happen when the new systems were using ipv6 and talking to each other that way while ther server was using ipv4. Even though the workstations had ipv4 enabled and could access the server, they did not show the server in the list.

Try to uncheck ipv6 on a windows 7 box's network adapter and reboot and see if it sees the server.
