There is no WinPcap 4.2. The latest version is 4.1.1.

Have a nice day

I am using 4.2.  Yes, it has happened again but this time I was able
to get it back without waiting until the next day.  Thanks

This is most probably a WinPcap issue, and not a Wireshark one.

Which version of WinPcap are you using?
When you encounter the issue, can you please report a bug as explained here:

Subject: [Wireshark-users] Vanishing interface

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.
