Dear All,

I have deployed windows service to communicate with OPC Servers.
The Windows service successfully connects with Kepware server and with DeltaV OPC Server
and performs read/write with respective OPC servers.
I am using Interop.OPCDotNetAutomation(Version 1.0.0.0) DLL to communicate with OPC Servers.

My problem is :

The win Service is unable to connect with other third party OPC server which is deployed as exe and giving the error as :
"Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE))"

The same piece of code which is used in Windows service runs fine in Windows Forms Application for that third party OPC server .

Could someone please advice me how to get rid of such exception.

Best Regards,
Mukund
