NM i found it.
Known bug- After upgrading to TCU 4.2 password to admin menus change to unknown default. In order to regain access to the menus you need to do the following:
1. Access Winscp to the tcu
2. E drive
3. Tandberg
4. DB
5. Add a .old to the end of the authentication file name. (note: you will need to copy the file over to your desktop to rename it then transfer it back onto the tcu)
6. Reboot TCU
