0x80070003 DCOM Error

Symptom

0x80070003 Directory not found is a DCOM error that occurs when the users try to connect to the OPC server but DCOM uses the wrong name for the OPC server folder (directory).

Cause

This typically happens when you move an OPC server to a different folder, or if you rename one of the folders in the OPC server path.

Repair Procedure

To repair this error, do one of the following:

Verify that the OPC server file is present in the project folder (for example, [Installation Drive]:\[Installation Folder]\GMSMainProject\bin). If not, reinstall Desigo CC.

Rename the folder with the correct folder name.
