I receive the following errors when I try to select an OPC server in the OPC Configuration block:

Cannot get Server List, Operation Returned
Error using ==> opcmex
The server process could not be started because the configured identity is incorrect. Check the username and password.


The Add... dialog box lists localhost as the host, server name is empty. The error occurs when I choose Select. Thiis doesn't happen on my Vista computer, just my XP SP3. When I choose select on the Vista computer, my OPC server applications are listed.

I went into the DCOM configuration in Component Services and explicitly entered my user info rather than "launching user". My account is Admin. I also set my opc server applications to run as my account. This error also occurs when I enter the name of the OPC server.

Any suggestions? I can only get it to work on my home computer(vista), not my work computer(xp)

Thanks
