Hi,
I will agree that this error says all and nothing. In most cases so far, the problem has been somewhat self-describing. Up til now. for simplify I worked through some methods, collectings and so (to fit our system needs) on a Console application. Now I move the focus to a web application and from no-where I got this error. -1073479673 "OPC operation failure". Of course, the code are still functioning from the console application (referring same assemblies).
The console app, opc-server & also the debugging-web-server are located on same machine. I feel this should be some kind of security concern (like that webserver and console app may run as different users) but not sure where to start (or if there are anything else to do).
Thank's in advanced,
