Unable to use nmap on Windows XP and 2000

[M.Ashcraft () epixtech com]

I downloaded the nmapwin_1.3.0.exe from www.insecure.org and installed per 
documentation. 

I can not get nmap or nmap win to function on Windows 2000 or Windows XP. 
In both nmap and nmapwin report "(0 hosts up)" no matter what I do.  It 
does not return immediately but takes about 30 seconds when scanning a 
single IP with default settings.  Enabling windows trace etc show that all 
is well.

I find the following error in the windows XP event log (Similar error is 
in Win 2000)

Event Type:     Error
Event Source:   Service Control Manager
Event Category: None
Event ID:       7000
Date:           10/23/2002
Time:           2:09:01 PM
User:           N/A
Computer:       MASHCRAFT-L
Description:
The Netgroup Packet Filter service failed to start due to the following 
error: 
The system cannot find the path specified.

I have read the docs.  I found that the system path had c:\program 
files\nmap\\bin and changed to c:\program files\nmap\bin.
I have verified that packet.dll and wpcap.dll exist.  XP does not provide 
system info as instructed.  Win 2000 shows npf as stopped. 

I have uninstalled wpcap and reinstalled.

Any ideas on where to go next.

Thanks,

Mike
