Take the 2-minute tour ×  We seem to have a problem with rogue
devices on our network. From DHCP (on Win2003), I can see names
of devices that are clearly not ours. From the name, I suspect
it's a wireless AP (WGR614 looks like a Netgear to me). I can't
ping it now, but I want to A.) be certain it's gone, and B.)
stop it from coming back.  My initial theory is to block the MAC
address at the switch. I'd also like to find which port the MAC
addy was connected to so I can find the location it was
connected.  We have different flavors of HP ProCurve switches,
with our primary switch a 4200. How would I go about doing this
as a one-off task? I'm not a network admin really, so please be
gentle.  Thanks, CC  share|improve this question Bad news:
blocking the MAC of the AP won't block the MAC of its connected
clients. You may want to have a look at procurve's port-security
(if compatible with your model) to only allow 1 mac per port. –
