Answer 1

Maybe your system user (by default MTSuser) is blocked.

Could you check the Identity properties of the Trimion Content Manager COM + application and retry logging in with this user.

Answer 2

The user ID running the Trimion Content Manager COM + application is correct. Check if the user exists and the password is correct.

Answer 3

Try restarting the COM service on the CMS server or restarting the CMS server (which will automatically restart the service). Thanks
