Всем доброй ночи!
На одном из клиентских компьютеров ни в какую не хотят вызываться методы WCF-сервиса.
Имеется простенький сервис такого вида:
//Интерфейс:
[ServiceContract(Namespace="http://XYZ/Config")]
public interface IService
{
[OperationContract]
string GetVersionPublic();
[OperationContract]
Stream GetFilePublic();
// и еще несколько схожих методов
}
//Реализация:
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Multiple, IncludeExceptionDetailInFaults = true)]
public class ServiceImpl : IService
{
public ServiceImpl()
{
}
#region IService Members
public string GetVersionPublic()
{
return "some text";
}
public System.IO.Stream GetFilePublic()
{
System.IO.FileStream stream = new FileStream("path...", FileMode.Open, FileAccess.Read, FileShare.Read);
return stream;
}
// + реализация оставшихся методов
#endregion
}
Хостится внутри win-службы. Конфиг сервера такой:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<services>
<service name="ServerLogic.ServiceImpl" behaviorConfiguration="myServiceBehavior">
<!-- Service Endpoints -->

Есть проблемная машина (не в нашем домене), на которой вызов любого(!) метода приводит к исключениям

Причем у всех остальных (а это почти 20 пользователей) все работает с абсолютно идентичными настройками и никаких исключений не кидает! Подскажите хотя бы куда копать...
