I have a Win2K LAN with two cabled pcs and one wireless, and internet
via a router. Up until two weeks ago my LAN function was good; however,
now PC1 (cabled) can't see the other two (cabled and wireless), and
neither of the other two can see PC1. Despite my efforts to enable it
(via TCPIP properties), ipconfig at command line still reports that
NetBIOS over TCPIP is disabled.

What might explain this? What else might explain why one pc has lost
sight of the other pc's? I've reconfigured network stuff, rebooted,
etc. Might I have a registry entry that needs reconfiguration? How can
I make ipconfig not report disabled NetBIOS?
