LAN + Networks

Really, this is a test of crossposting - also tho it is a record of an issue I've been having recently on the LAN - until about mid-may all computers on the LAN would show up on the Network Neighbourhood Window - like this picture:

Now however only a handful are showing up - although they can still be accessed via 'map network drive' - you just have to know the right name. I think the culprit is an WinXP patch update I did a while ago, although that doesn't explain why some of the linux comps are no longer coming up.
