A mapped network drive is a convenient way to access shared folders or files on another computer, server, or network storage device as if they were part of your own PC. Once mapped, the drive normally appears in File Explorer under This PC, with a drive letter such as Z:, Y:, or X:.
But sometimes Windows refuses to show a mapped network drive even though you created it successfully. You may still be able to access the shared folder using its network path, while the assigned drive letter is missing from File Explorer. In other cases, the drive appears briefly and then disappears after restarting your computer.
This can happen because of network connectivity problems, incorrect credentials, drive mapping settings, Windows services, permission issues, or User Account Control settings. Fortunately, you can work through several straightforward fixes without being an advanced Windows user.
In this guide, you’ll learn how to troubleshoot a mapped network drive not appearing in Windows and get it showing up again.
Mapped Network Drive Not Appearing in Windows [Fix]
To fix a mapped network drive that is not appearing”
- First, confirm that your computer is connected to the correct network and check This PC in File Explorer.
- Open File Explorer > This PC and use Computer > Map network drive to verify or recreate the missing mapping.
- Check the mapped drive’s network path, drive letter, and credentials to make sure Windows is using the correct information.
- Restart the Workstation service and related networking services if Windows cannot connect to the shared location.
- Turn on Network Discovery and File and Printer Sharing when the computer or shared device cannot be found on your network.
- Check Windows permissions, shared-folder permissions, and saved credentials if the mapped drive connects but remains inaccessible.
- If the drive is missing only in applications opened with administrator privileges, check User Account Control and mapped-drive settings.
- Reconnect the drive after restarting Windows and enable Reconnect at sign-in so the mapping can return automatically.
Before changing anything, it helps to understand what you’re actually troubleshooting. A mapped drive is essentially a shortcut that connects a drive letter to a network location. For example, Z: might point to \\Server\Documents.
Work through the following steps in order. After each major fix, check File Explorer > This PC to see whether the drive has returned.
Step 1: Check File Explorer for the Missing Drive
Start with the simplest possibility. Open File Explorer by pressing Windows + E, then select This PC from the left side of the window.
Look under Network locations and check whether your mapped drive is listed there. If you don’t see it, click the three-dot menu at the top of File Explorer and select Options if necessary. You can also close and reopen File Explorer because a temporary Explorer refresh issue can sometimes prevent a newly mapped drive from being displayed.
Next, verify that you are connected to the network where the shared folder is located. If the drive belongs to an office server, NAS device, or another computer, make sure your PC is connected to the appropriate Wi-Fi or Ethernet network.
If you’re working remotely, remember that a company network drive may require a VPN connection before Windows can reach it.
Step 2: Check Whether the Network Location Is Accessible
If you know the network path, test it directly instead of relying on the missing drive letter.
Press Windows + R to open the Run dialog. Enter the network path, such as \\ServerName\SharedFolder, and press Enter.
If the shared folder opens, your network connection is probably working and the problem is more likely related to the drive mapping itself.
If Windows reports that the network path cannot be found, focus on your network connection first. Check whether the server or other computer is powered on and connected to the same network. You can also try accessing another shared folder if one is available.
Step 3: Recreate the Network Drive Mapping
If the old mapping is damaged or no longer points to the correct location, recreating it is often the quickest solution.
Open File Explorer > This PC. Select the three-dot menu > Map network drive. Choose the drive letter you want to use, such as Z:.
In the Folder box, enter the correct network location, for example \\ServerName\SharedFolder. If you want Windows to restore the connection automatically whenever you sign in, select Reconnect at sign-in.
If the shared folder requires a different username, select Connect using different credentials. Then enter the appropriate account information when Windows asks for it.
Click Finish and give Windows a moment to establish the connection. Return to This PC and check whether the mapped drive now appears.
Step 4: Check the Drive Letter
Sometimes the network location is fine, but the selected drive letter is already being used by another device or connection.
Open File Explorer > This PC and look at the drive letters currently assigned to your computer. If the letter you previously used is now occupied, recreate the mapping with another available letter.
For example, if Z: is already assigned, try Y: or another unused letter.
The important thing is to use a drive letter that isn’t already assigned to another storage device or network location. After changing it, reconnect the network drive and check This PC again.
Step 5: Enable Network Discovery and File Sharing
If Windows cannot properly detect other computers or shared devices on your network, check your sharing settings.
Open Settings > Network & internet > Advanced network settings > Advanced sharing settings. Under the appropriate network profile, turn on Network discovery and File and printer sharing when appropriate for your network.
Be careful when enabling sharing on public networks. These settings are generally more appropriate for a trusted private network, such as your home or workplace network.
Once you’ve changed the settings, restart File Explorer and try opening the network location again.
Step 6: Restart the Workstation Service
Windows relies on networking services to maintain connections to shared resources. If one of these services is stuck, a mapped drive may stop appearing or connecting correctly.
Press Windows + R, type services.msc, and press Enter.
Find the Workstation service in the list. This service helps Windows maintain network connections to shared resources. Right-click it and choose Restart.
If the service is stopped, choose Start instead. You can also open its Properties and check that its startup setting allows it to start with Windows.
After restarting the service, reopen File Explorer > This PC and check your mapped drive.
Step 7: Check Your Network Credentials
A mapped drive can disappear or fail to reconnect when Windows no longer has valid credentials for the remote computer.
Open Control Panel > Credential Manager > Windows Credentials. Look for credentials associated with the server, NAS, or computer hosting your shared folder.
If the saved credentials are outdated, you may need to remove the old entry and reconnect to the network location using your current username and password.
Be certain that you know the correct credentials before deleting a saved entry. Once you reconnect successfully, Windows can save the updated information if you choose that option during the connection process.
Step 8: Check Folder and Network Permissions
Sometimes the drive mapping itself is not the problem. Your account may simply no longer have permission to access the shared folder.
Try opening the network path directly using Windows + R. If Windows displays an access-denied message, contact the administrator of the shared computer or server and verify your share permissions and NTFS permissions.
If you’re managing the shared folder yourself, check that the account you’re using has the necessary access rights. A password change or account modification can also cause a previously working network drive to stop connecting.
Step 9: Check Administrator and User Account Differences
Here’s a less obvious problem that can make users think their mapped drive has disappeared.
A mapped network drive can sometimes be available in your regular Windows session but unavailable inside an application running with administrator privileges. This happens because Windows can maintain separate network-drive views for different security contexts.
If the drive appears normally in File Explorer but disappears when you open an elevated application, this may be the reason.
In that situation, don’t immediately delete and recreate everything. First determine whether the problem occurs only inside applications launched with administrator privileges. If so, you may need to adjust how the application accesses the network location rather than changing the drive mapping itself.
Step 10: Restart Windows and Test the Mapping Again
After making the previous changes, restart your computer. This gives Windows an opportunity to reload the network services and reconnect the mapped location.
Once Windows starts, connect to your normal network and wait a few seconds. Then open File Explorer > This PC.
Check whether the mapped drive is visible. If you selected Reconnect at sign-in while creating the mapping, Windows should attempt to restore the connection automatically.
If it still doesn’t appear, recreate the mapping one more time and carefully verify the drive letter, network path, username, password, and network connection.
FAQs
Why is my mapped network drive not showing in File Explorer?
The most common causes include a lost network connection, incorrect credentials, a changed network path, a disabled networking service, or a mapping that was not configured to reconnect after signing in. Start with File Explorer > This PC, then test the network path directly.
Why does my mapped drive disappear after restarting Windows?
The mapping may not have been configured to reconnect automatically, or Windows may be unable to authenticate with the remote computer after startup. Recreate the mapping and select Reconnect at sign-in.
This usually means the network connection itself is working, but the drive mapping or drive letter has a problem. Recreate the mapping through File Explorer > This PC > Map network drive.
Why does my mapped drive appear in File Explorer but not in an application?
The application may be running with different administrator privileges, causing it to see a different set of mapped network drives. Test whether the problem occurs specifically with applications launched as administrator.
Can I use another drive letter for my network drive?
Yes. If the original drive letter is already assigned to another device or connection, choose an unused letter when creating the mapping.
