Windows Service as Remoting Host: Requested Service Not Found

[Fadi]

Backround:
I am trying to figure out how to do the equivalant of a classic COM
Local Server Singleton in .NET/C#. I created a coupld of simple Class
Libs that exposes public interfaces and hosted them in a Windows Forms
EXE. Create a Windows Forms client and both the Client and the Host
EXEs configure the remoting protocols through respective .config
files.

Problem:
I want to change the host from an Win Forms EXE to a Windows Service.
The Windows Service is build and installed and I can start it
successfully but i am unable to communicate with the objects it hosts!
I get the error: "Requested Service Not Found".

I override InitializeLifet imeService() in both hosted objects to
return 'null' so the lease never expires, but w/o success in resolving
this error.

Thanks in advance...

Fadi,

In the Windows Service, where are you creating the remote object? How about
code snippets of the service.

Hi Steve,

Thanks for the reply. The Windows Service (ComponentsServ ice.exe)
simply calls:

protected override void OnStart(string[] args)
{
string remConfig =
System.AppDomai n.CurrentDomain .SetupInformati on.ApplicationB ase +
"ComponentsServ ice.exe.config" ;
RemotingConfigu ration.Configur e(remConfig);
}

The client app simply uses 'new' to create and comm with the remoted
objects.

Note that this works perfectly the the Host is a Win Forms EXE (which
i have to deliberately launch before the remote objects it hosts can
be accessed by the client)

Thanks
