Return Membership Through WCF Service

Question

I have a WCF service to get users from ActiveDirectory. I get the parameter from the request (username) and create a response with the MembershipUser property. for some reason the connection is approaching. the service operation finds the user and successfully creates a response. when executing a line: "return response"; I have a client side exception. Exception: the underlying connection was closed: the connection unexpectedly closed an internal exception: Response = null Status = System.Net.WebExceptionStatus.ConnectionClosed

thank!
