Hi,

I am not able to connect to OPC server for non admin user in windows server 2003.

I get Runtime error '-536608665(e0040067)':
Failed to connect OPC server.
The system returned the following error message:
Access is denied

But i can connect non admin user to opc server in Windows xp

Is it possible for non admin user to connect OPC server in windows server 2003?

OPC server and client are on same system

Please give me your feedback

Thanks!
Santosh

From what I've read on this thread, you'll need to set computer-wide DCOM security permissions. You'll want to peruse that thread.

On another note, this isn't really the best spot for this question. An error message isn't a crash, hang or bsod, and the situation is more relevant to specifically the Windows Server section (even though OPC servers can and often do exist in many client versions of Windows). You'll be able to receive more help there, as it's pertinent to your needs.
