Communication Between Two WCF Services

[battula32]

Hi,
I have two WCF Services say Ser1 and Ser2. Both services are running in two different machines and both services are Windows services. I want to communicate those two services. Is it possible?.
Here Clien1 is client to Ser1 and Client2 is Clinet to Ser2.
Cliet2 Reqeusts/Sends data to Ser1 through Ser2 and Client1 Requests/sends data to Ser2 through Ser1. This we need to break

Data transfer between Ser1 and Ser2 is not happenening if these servers are as Windows Services. But we can able to communicate if these Ser1 and Ser2 are console apllications.

Rest of the configurations like App.Config and Proxies are exactly same for both as a Service or as a Console application.

I want to konw why both servers are not communicating if I configure these as Service or Process?
Why communication is possible only if these servers are console applications.

Thanks and regards

Hi,

I am getting this exception

if you have IIS running on both you can use Web services

No,

I am not using WEb service, It is windows service and I am using netTcpBinding.

if the services do any! type of GUI
they have to be run as
Log on as:
Local System acount
and have "allow service to interact with desktop
under the service's properties in services

[battula32]

This Service is not GUI type of service.

Client can able talk with this service. If client calls any method of that service, Sevice has to invoke a method in other service using WCF service contract, But it is failing here, If I run these services as console applications, It can able eto invoke other server method.

Hi

I solved it. Actually the problem is not with coding or configuration. The proble is with security settings.Earlier I launched this server as Local system account. Now I changed to Administator account. It starts working
