[Winpcap-users] capture session could not be initiated

[Gianluca Varenni]

Uhm, are you sure you are using WinPcap 3.1, and not one the 3.1 
alphas/betas?

This (misleading) error reported by Windump has been fixed in WinPcap 3.1.

Can you please tell me the output of Windump -V?

The corrent output with windump 3.9.3 and winpcap 3.1 (on Windows XP) should 
be like this

windump version 3.9.3, based on tcpdump version 3.9.3
WinPcap version 3.1 (packet.dll version 3, 1, 0, 27), based on libpcap 
version 0
.9[.x]
Usage: windump [-aAdDeflLnNOpqRStuUvxX] [ -B size ] [-c count] [ -C 
file_size ]
                [ -E algo:secret ] [ -F file ] [ -i interface ] [ -M 
secret ]
                [ -r file ] [ -s snaplen ] [ -T type ] [ -w file ]
                [ -W filecount ] [ -y datalinktype ] [ -Z user ]
                [ expression ]


Have a nice day
