Network (ping) Issue

[slomustang]

I'm helping a local group get their computer lab running and have run into an interesting issue. Let me give some background:

9 workstations (WinXP Pro)
1 lab monitor workstation (Win2000)
all can access internet

192.168.1.1 gateway
192.168.1.2 lab monitor
192.168.1.3-11 workstations

The workstations can ping anyone and anywhere, BUT the lab monitor can only ping itself and internet addresses. Basically, all remote administration programs work (Compuguard, Remote Administrator) and they can see each other via My Network Places.

Any idea why this would occur?



Yes, this set-up is *similar* to the one I discussed last year:

check your routing tables.

it also seems (from the other post) that you're running 2 nic's in the monitor.

you need to assign different sub-nets to the nic's otherwise you're confusing the routing tables.

what seems to happen in your scenario is that all pings go only to one physical nic by default. (which is correct behaviour)

Sorry, just one nic in the lab monitor computer (I'm discussing a different network).

SurfControl isn't working properly yet, but I don't *think* it has anything to do with this issue. . .but we'll see. The switch has been set-up (by their IT staff) to mirror the ports with the incoming internet connection and the lab monitor computer. During set-up SC asks you to bind the appropriate nic to the program.

Anyways, the same issue was present even after uninstalling SC.

nevermind.

I'm assuming you have the win XP's and 2k in the same workgroup ?

Ping, aka echo, may be disabled on the machines you are trying to ping. IIRC this setting is a checkbox in the XP firewall's "Advanced" tab.
