Remapping a network drive means telling your computer to connect to a shared folder using a new path or location

When a network drive stops working — because the server moved, the folder path changed, or you switched networks — you don't start from zero. You disconnect the old broken link and create a new one pointing to the correct location. The process takes about five minutes and works the same way on Windows and Mac, though the exact steps differ slightly.

The most common reason to remap is that your IT department or network administrator moved the shared folder to a different server, changed the folder name, or you're now on a different network than before. Sometimes a drive just stops responding because the server it pointed to is offline. Remapping fixes all of these by breaking the old connection and building a new one with current information.

Key Takeaways

  • You must first disconnect the old network drive before creating a new one, or Windows will reject the duplicate letter assignment.
  • The new network path (usually something like \\servername\foldername) must be correct before you start, so confirm it with your IT department or network administrator first.
  • On Windows, use File Explorer to disconnect, then use "Map network drive" to reconnect; on Mac, use Finder's "Connect to Server" option.
  • After remapping, test the connection by opening a file from the drive to confirm it's working before you rely on it for work.

Disconnect the old network drive on Windows

Open File Explorer and locate the network drive in the left sidebar under "This PC" or in the main window. Right-click on the drive letter and select "Disconnect." Windows will when ready sever the connection. If the drive is in use by an open file or program, Windows will warn you — close that file first, then try disconnecting again.

If you cannot see the drive in File Explorer, open a Command Prompt window (search for "cmd" in the Windows search box) and type net use to see all connected network drives. Find the one you want to remove, note its letter, then type net use X: /delete (replace X with the drive letter). Press Enter and the connection is gone.

Get the correct network path before you start

Before you create a new connection, you need the exact network path to the shared folder. This usually looks like \\servername\foldername or \\192.168.1.100\shared. Ask your IT department or network administrator for this path — do not guess. If you use the wrong path, the drive will appear to map successfully but will fail when you try to open it.

If you're remapping because the folder moved but you're not sure of the new path, contact whoever manages the network before you proceed. They can also tell you whether you need a username and password to access the new location, which you'll need during the remapping process.

Map the new network drive on Windows

Open File Explorer, right-click on "This PC" in the left sidebar, and select "Map network drive." A dialog box will open. Choose the drive letter you want to use (it can be the same letter as before, since you already disconnected the old one). In the "Folder" field, type or paste the network path you confirmed with your IT department.

Check the box for "Reconnect at sign-in" if you want Windows to automatically reconnect this drive every time you log in. If the shared folder requires a username and password different from your Windows login, check "Connect using different credentials" and enter those details. Click "Finish" and Windows will attempt to connect.

If the connection succeeds, the drive will appear in File Explorer with the letter you assigned. If it fails, Windows will show an error message — the most common ones are "The network path was not found" (wrong path) or "Access denied" (wrong username or password). Go back and verify both with your IT department.

Remap a network drive on Mac

Open Finder and click "Go" in the menu bar at the top. Select "Connect to Server." A dialog box will appear. Type the network path in the "Server Address" field — on Mac this is usually smb://servername/foldername or smb://192.168.1.100/shared. The "smb://" prefix tells Mac you're connecting to a Windows-style shared folder.

Click "Connect." If the server requires a username and password, Mac will prompt you for them. Enter your credentials and click "Connect" again. If the connection works, the shared folder will appear on your Mac desktop and in Finder's sidebar. If it fails, check the network path and credentials with your IT department, the same way you would on Windows.

Unlike Windows, Mac does not automatically reconnect network drives at login by default. If you want this drive to reconnect every time you log in, open System Preferences (or System Settings on newer Macs), go to "General" > "Login Items," and drag the mounted network drive into the list.

Test the connection before you rely on it

After the drive maps successfully, open it and try to open or create a file. This confirms that the connection is not just visible but actually working. If you can read and write files, the remap is complete. If you get an error when you try to open a file, the drive may have connected but lacks the correct permissions — contact your IT department to confirm your access level on the new location.

If the drive worked for a few hours or days and then stopped responding, the issue is usually that the server went offline or your network connection dropped. Disconnect and remap again using the same steps. If this happens repeatedly, ask your IT department whether the server is stable or whether you should use a different backup location.

Frequently Asked Questions

Can I use the same drive letter as before?

Yes, but only after you disconnect the old drive first. Windows does not allow two network drives to use the same letter at the same time. Once the old connection is gone, you can assign that letter to the new one.

What if I don't know the network path?

Contact your IT department or network administrator. They manage the shared folders and can give you the exact path. Do not try to guess — a wrong path will appear to work but fail when you try to use it.

Why does the drive show up but I can't open files?

The connection succeeded but your user account does not have permission to access that folder. Ask your IT department to confirm that your username has read and write access to the new location.

Do I need to remap if I just restart my computer?

No, if you checked "Reconnect at sign-in" during the mapping process, Windows will automatically reconnect the drive when you log back in. On Mac, you may need to manually reconnect unless you added it to Login Items.
