hi Team,

we are facing a strange issue. From my development VDI which is in domain 'A' and able to connect all the services which are hosted in servers of Domain Type 'B'. But When I am connecting to one service I am getting an exception.

message:

The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'Negotiate,NTLM'.
source: mscorlib

targetsite: Void HandleReturnMessage(System.Runtime.Remoting.Messaging.IMessage, System.Runtime.Remoting.Messaging.IMessage)

stacktype: System.ServiceModel.Security.MessageSecurityException

stacktrace:
