I have a problem with a new web service that uses windows authentication. When a call the web service more than once from the client method, I'll get a timeout error. Surely it has something to do with the authentication, if I remove the windows authentication from the web site everything works fine.
WebService1 Shipping = new WebService1();
Shipping.Credentials = new System.Net.NetworkCredential(user,password);
DataSet AppCust = Shipping.GetNotApprovedCust();
// Next call fails
