Currently I am using this low-end machine (Windows 2000 OEM, dial up)
for passive monitoring to debug application, firewall, security and
LAN issues via the generic adaptor & the WAN (PPP/SLIP) interfaces
working in tandem. This has worked very well. Or, at least, until
yesterday.
Yesterday, somehow I lost the WAN (PPP/SLIP) interface. Without that
interface, there was no capturing - unless one performs the
installation of the virtual loopback adapter.
Here is what I did. When the WAN interface vanished yesterday, I
attempted to restart the box and then log on with WS. No Wan
interface. Today I booted up and again started up WS. Today both
interfaces were back.
Here's my question: Why did I loose the interface in the first place?
Since this interface originates from the WAN (for which I have no
visibility) could this be a DCHP lease issue or an ACL issue or ?
Many thanks.
