DCOM Losing Credentials - System 800xA 6.0.3-2
Dear, I am facing an issue with System 800xA 6.0.3-2 and 3rd party OPC client communication. Periodically this communication is lost and I must reauthenticate DCOM user to recover it.
I do have 800xA OPC Client Connection licenses available and DCOM user has LogonAsAService privilege.
Has anyone faced this situation before? Any tips?
Best regards,
Marco

Did you try restarting the server and client nodes once?
Is the option Password Never Expires enabled for the OPC user?
May be you can send snapshots of the DCOM settings configured. May be then we can identify the problem.
You can also refer 3BDS011222* manual for reference.

Hello,
If you are running the GPO then ensure "logon as service" group should have the rights for the user used for DCOM else on every restart DCOM will fail and needs to relogin again to respective services (windows).
Don't change the default domain policies instead change the precedence order and check/add the user to "logon as service group".
clue: check windows system logs with event ID and google for how to change the GPO.
