Step one
Start by opening file explorer in windows.
Step two
Once inside the file explorer go to the "this pc" tab.
After you've entered the "this pc" tab, you would want to press the three dots on the top of the screen.
Once you've done that dropdown menu will appear, just click map a network drive.
From there you will be met with this screen, choose your drive, for demonstration purposes i choose "y".
Once you've choosen your drive select the folder box and type what is shown on the screen, note that where I put username you will put your own same with the domainname. And make sure that "recconect at sign-in" is checked off."
The final step is to sign in with you domain credentials, click "remember me" to make the sign in process easier next time.
