The remote operation failed. error while connecting to Remote biztalk server.

Question

Hello,

I have one application which gets the information of all devices on present on Biztalk. It works fine for the lines of code given below.

         deviceManagerProxy = new DeviceManagerProxy("localHost");

        DeviceDefinition[] devices = deviceManagerProxy.GetAllDevices();

But if I change localhost to some remote computer say "192.108.1.1" or computer name say "VISHNU" the error comes "The remote operation failed."

         deviceManagerProxy = new DeviceManagerProxy("VISHNU");

        DeviceDefinition[] devices = deviceManagerProxy.GetAllDevices();

I can ping to the machine "VISHNU" from command prompt. Also I checked that the RFID manager is running on the "VISHNU".

Can some one guide me?
