generate code" for ".NET 2.0"

I tried my webservice in soapUI PRO, it works fine. The results display nicely.

I use "generate code" for ".NET 2.0" to generate a c# class, but the generated c# class was not working. The generated class should get same result as in soapUI PRO, right?  Following is the error message:"

SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

C#

Employee client = new Employee();
client.ClientCertificates.Add(GetCertificate()); // works fine
var f = client.GetEmployees(); // error

any help?
