Hey!
After granting easy access the computer still ask for a password when I try to connect to it. Any ideas about fixing it remotely?
When I install MSI, beside easy access granting is always imported REG or newly TVOPT file with "backdoor" password configured for cases like yours - access granting not done correctly for some reason.
For Windows you could ( when computer reachable by PSEXEC in "internal" network ):
1. Enable RDP by PSEXEC + CMD by registry modify enable RDP and this way by RDP configure TeamViewer manually to grant access by GUI.
2. PSEXEC + CMD start command: TeamViewer.exe assign --api-token <APITOKEN> [--group-id <GROUP_ID> --grant-easy-access --reassign --proxy <YOUR_PROXY> --proxy-user <YOUR_PROXY_USER> --proxy-pw <PASSWORD>]
I was looking for, but not tested some portable VNC Server for such case - you could try out.
