raw socket error in web service

Xu Ying

Hi,

I write a web service to send ICMP using raw socket in C#.
When calling the sendto() method of Socket, an error
accurs and prompts:

System.Net.Sockets.SocketException: Socket access denied.

I logon win2k as Administrator. I have no idea what's wrong

Could anybody help me? Thanks.

Web Services run under the ASPNET system account. By Default this account
has very little permissions and cannot perform operations like Opening a
socket, writing to arbitrary files, running programs etc...

You will have to give your ASPNET account more privileges (with caution).

Thanks for your kind help.
Just as you said, after I gave ASPNET account more
privileges and restarted IIS, the problem solved.
