The issue was not with Twingate. The server the customer was trying to remote into was refusing access, but changing the password allowed the customer to sign in normally.
Updated the customer's Microsoft Office applications from the 2013 version to the latest 365 version. Applied necessary updates and efficiently demonstrated the new Outlook layout to the client.
The MBSERVER has been rebooted and all systems are operating as intended.
The printing issues have been resolved by networking all devices. The server was not able to print via redirect, so a network connection was established to add the printer. All functions are now working as expected.
The status of the backups has been checked and they are currently operating correctly.
The customer named Jackie has been successfully logged in.
Upon logging in, the client was provided with instructions on signing out other users who may not have properly signed out. It was emphasized that this temporarily addresses the issue while we work towards a permanent resolution.
