Nmap Development: nmap run error

["ihug01" <hong2005 () ihug com au>]

Dear Sir,

I have downloaded a namp v1.3.1 GUI running on windows NT 4.0 with Network Monitor Protocol installed. When I run your 
nmap,the namp windows popup and seems everything is ok.

But when I try to scan my private network host 192.168.0.2, the following error comes out. all other settings is by 
nmap default.I only input the IP and click "scan" buttom.

Starting nmap V. 3.00 ( www.insecure.org/nmap )
Port 5000 proto udp is duplicated in services file D:\NMapWin\bin/../data/nmap-services
You need raw support for this.
 run "nmap --win_list_interfaces --win_trace" to troubleshoot
QUITTING!

So I try to run "nmap --win_list_interfaces --win_trace" under command line,
my machine says:

***WinIP*** initializing if tables
***WinIP*** if tables complete :)
***WinIP*** trying to initialzing winpcap 2.1
***WinIP*** delay load error
failed to load DLL: packet.dll
***WinIP*** winpcap is not present
***WinIP*** don't try rawsock
***WinIP*** o.isr00t = 0
available interfaces:

name    rawsend    raw recieve     ip
loopback0  none      none        127.0.0.1
eth0       none      none        192.168.0.21   



please give me some tips.

Thanks a lot!
