[Cialug] Slightly OT, .. Troubleshooting a network?

[L. V. Lammert]

Have a problem with a small network (six machines, one server & router) -
some of the Windoze machines are taking *minutes* tologin on the server,
and I suspect that some of the network gear/cabling may be having
problems.

Other than pawing through packet dumps or ramdonly running cables to
byass what's in the walls, is there any way to collect 'statistics'?
Collisions? Packet re-sends? Conversation failures?

	TIA,
