Computer A (new main) computer ethernet connected to D-Link Router
Computer B (old) computer ethernet connected to D-Link Router
Computer C (laptop) wirelessly connected to D-Link Router

"All" computers can see Computer B & C in Network Places and can share files
and B & C can see and use printers on Computer A.

All computers running XP with SP2, except Computer B doesn't have SP2 (won't
update properly -- but B works fine).

However, "nobody" can see Computer A in Network Places.

Any thoughts -- this is driving me crazy -- trying to move files around.
