Wireshark-users: [Wireshark-users] Default Interface

Dear all,

Sorry if this has been asked before, but I couldn't find it in the archives.

I'm running Wireshark 0.99.5 (SVN Rev 20677) on:

Windows 2000 SP4, build 2195 with WinPCap version 4.0 (packet.dll version 4.0.0.755) based on libpcap version 0.9.5, without AirPcap.

When I start Wireshark, if I select "Capture" -> "Start" I get a message about being unable to open the capture interface. I have gone in to the capture section of the preferences and set the Default Interface to the actual iterface but that doesn't seem to help.

What I have noticed though is that when I open the Capture Options dialog, the selected interface says something like:

\Device\Packet_{<long guid thingy>}

However, when I drop the box down and select the real thing (the one that works) it is listed as 

<Name of the device>: \Device\NPF_{<same long guid thingy as above>}

Am I doing something wrong? Is there a way to sort this out?

Thanks
