3 Computers One network - No connection to XP bos

I have lost the ability for my two wireless computers to see the "main" computer.
The situation is that the hard-wired home station is on XP Pro - SP3 and it is unseen by the other two computers.
One is Vista 64, the other is 7Ultimate.
Also, the windows
updates for the XP bos are no longer loading and expecting the disk, which it can't have as this is an updated system with a ghosted OS.
So, the Vista and the 7 see each other, but I can't get to the XP box or the printers.
I have made sure that file sharing
is on, the McAfee was off, redone the home network software and still no luck.
Please help in easy steps, as I am losing what is left of my mind! Thanks,
