<DIV><FONT size=2>In practice the driver needs to be started with admin -
elevated privileges, for example running your program by right-clicking on it
and choosing "run as administrator". What Wireshark does is changing a registry
key so that the NPF driver gets loaded automatically upon boot. This same option
will be available in the next version of the WinPcap installer (and it will be
enabled by default).</FONT></DIV>

NPF Driver Issue</DIV>
<DIV><BR></DIV>After installing Winpcap 4.0.2 on Windows Vista our capture
application (DICOM Network Analyzer) is not able to see the Network
Interfaces. The issue seems to be related to the NPF driver not running. But
actions to enable this via net start npf don't work.<BR>If I install Wireshark
and during setup choose the option to install and enable the NPF driver the
problem is resolved. Is there an additional step that needs to be performed to
make Winpcap work on Windows Vista in either the setup or the application
using Winpcap?<BR> <BR>DVTk Team.
