If you are NOT on the company network, you will need to connect through VPN

If this is the case, hit the VPN button. This will connect you to the corporate network remotely.
Once you are connected, hit the “Connect” button to finish the process.

At this point, the PC will join the domain and restore the data. Depending on how much data you have, this could take anywhere from a few minutes to over 30 minutes.
If you have connected through VPN, you will be asked to authenticate. Type in your Corporate ID and password to authenticate.
