Service not working in Network?

[Guest]

hi all,

I have written a C# Service which is a Server accepting Clients,It is
working fine when i connect from localhost but when i connect from any other
machine to my machine , the service is not working, the Service is in
"Network Service".....i even tried "Local System" and also "Local Service"
but the end result is , it is working only for Localhost connections and not
for Remote Connections...

the code for server is as follows..

////////////************Server Code starts here**********//////////////////
IPAddress ipAddress = Dns.Resolve("localhost").AddressList[0];
TcpListener listener = new TcpListener(ipAddress,portNum);
try
{
listener.Start();
TcpClient handler = listener.AcceptTcpClient();
////extra things done here
}
////////////************Server Code starts here**********//////////////////

but the remote connections are not getting connected.......why so?

with regards,

How would you like your clients to connect if you bind your listener to
'localhost' which resolves to 127.0.0.1?
You have to use your real host name, not the loopback address.

I wouldn't know, but I guess it's more likely a bug than a network problem.
I would try to telnet with your service (telnet servername port), to see
wheter it's a server or a client issue.

There must be something wrong in your C# client, step through it in the
debugger and look where it waits.
