Nmap not working with Vista

[Gaston Martin]

I've just installed last stable version of NMAP  (4.50),  and It doesn't
work with Vista.

 

I'm getting this error:

 

WARNING: Could not import all necessary WinPcap functions.  You may need
to upgrade to version 3.1 or higher from http://www.winpcap.org.
Resorting to connect() mode -- Nmap may not function completely

TCP/IP fingerprinting (for OS scan) requires that WinPcap version 3.1 or
higher and iphlpapi.dll be installed. You seem to be missing one or both
of these.  Winpcap is available from http://www.winpcap.org.
iphlpapi.dll comes with Win98 and later operating sytems and NT 4.0 with
SP4 or greater.  For previous windows versions, you may be able to take
iphlpapi.dll from another system and place it in your system32 dir (e.g.
c:\windows\system32).

QUITTING!

Hi,

I'm afraid there's a problem with the setup file for nmap 4.50 (which has
been corrected in SVN and hopefully should be available on the website
early next month), it doesn't install WinPcap correctly on Vista. The
easiest way to get it working is probably to re-install WinPcap correctly
using the (tiny) setup file found at:

http://www.winpcap.org/install/default.htm

If you have UAC enabled, you may also want to consider changing a registry
setting to make it easier to use nmap:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NPF\Start

Change the value to 2 (instead of the default of 3), and after a reboot of
Vista you should be able to use a Standard User or a normal Command Prompt
(rather than an elevated one) when running as an Admin user.
