File Explorer crashes or freezes while accessing Mapped Network Drives

If File Explorer crashes or freezes while accessing Mapped Network Drives on your Windows 11/10 system, this post may help you fix it. At times, you may see error code c0000374. This issue prevents users from accessing the data inside the mapped network drives because every time users try to access them, File Explorer either freezes for a long time or crashes.

Explorer crashes or freezes while accessing Mapped Network Drives

The following solutions may help you fix the issue:

1. Unpin everything from Quick Access.
2. Set File Explorer to open to This PC instead of Quick Access.
3. Turn off the Thumbnails Preview in File Explorer.
4. Clear the File Explorer’s history.
5. Disable Windows Search Service.
6. Create a new Value in Windows Registry.
7. Disable Fast Startup.

Let’s see all these solutions in detail.

1] Unpin everything from Quick Access

We can pin files and folders to the Quick Access menu. This allows us to access such files and folders quickly. But pinning files and folders to Quick Access sometimes causes the File Explorer to hang or freeze. Hence, if you have pinned anything to Quick Access, remove it and see if it brings any changes.

2] Set File Explorer to open to This PC instead of Quick Access

You may also experience this issue if the File Explorer opens to Quick Access by default. Set File Explorer to open to This PC instead of Quick Access and see if it fixes the issue.

1. Open File Explorer.
2. Click on the View menu and select Options. If you are a Windows 11 user, click on the three horizontal dots in the File Explorer and then select Options.
3. In the Folder Options window, make sure that you have selected the General tab.
4. Select This PC in the “Open File Explorer to” drop-down menu.
5. Click OK to save the changes you have made.

3] Turn off Thumbnails Preview in File Explorer

Among the affected users, some have explained that the issue was fixed when they disabled the Thumbnail Preview in File Explorer. You should also try this.

4] Clear the File Explorer’s history

You can also try to clear the history of File Explorer. This action clears the search history and the list of all files and folders that you have opened in File Explorer. In addition to this, deleting the File Explorer history also clears the cache. Hence, it also fixes the problems that arise due to the corrupted cache.

5] Disable Windows Search Service

If the above methods did not fix your issue, disabling the Windows Search service may help. To do this, follow the steps below:

1. Press Win + R hotkeys and type services.msc . Click OK.
2. In the Services app, scroll down the list and find Windows Search.
3. Once you find it, double-click on it to open its Properties.
4. Under the General tab, select Disabled in the Startup type drop-down menu and click on the Stop button.
5. Click Apply and then OK to save the settings.

After disabling the Windows Search Services, check if the issue still persists.

6] Create a new Value in Windows Registry

Another method to fix this issue is to create a new Value in Windows Registry. We have listed the instructions for this below. But before you proceed, it is better if you create a backup of the Registry so that you can restore it if any problem occurs.

1] Press Win + R hotkeys to launch the Run command box. Type regedit and click OK. Click Yes if you receive a UAC prompt message.

2] In the Registry Editor, copy the following path, paste it into its address bar, and hit Enter:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider

3] Make sure that you have selected the NetworkProvider key on the left side. Now, right-click on the right side and go to “New > DWORD (32-bit) Value.” Name this newly created Value RestoreConnection. Now, double-click on it and set its Value Data to 0.

This has helped many.

• This has also been known to help some. Add the registry key ProviderFlags as a REG_DWORD with a value of 1 (0x00000001) to HKEY_CURRENT_USER\Network\*SMBv1 Drive Letter Then reboot the computer and see.
• Yet another suggestion that has helped some is to navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters and create a DWORD DisabledComponents with value 00000020.

7] Disable Fast Startup

Fast Startup is a feature in Windows 11/10 computers that decreases the bootup time in order to start Windows quicker than the normal mode. Sometimes, it creates issues with Windows OS. You can disable the Fast Startup feature.
