- If the drivers recently got a letter change, this error could arise. Similarly, if there is a different letter or a missing letter, this error can occur. After all, drive mapping was done with another letter in the data.
- Maybe you have file and printer sharing disabled. Typically, this happens in the Firewall settings, and you might have to check it out.
- Remember always to have some space in your root drives of the network servers. Keep the space clear on both sides. If you don’t have enough space, the error can surface.

The very first thing that you should try is remapping the drive. Yes, it is one of the most effective solutions.
- Open the command prompt, make sure to do it with Admin permissions. So, right-click on the Start Menu and select Command Prompt (Admin). If you don’t have this option, use Run (Windows + R). Type ‘cmd’ and press Shift + Enter to run it as Admin.

2. The File And Printer Sharing Fix
You might have to enable File and Printer Sharing from the Firewall settings. If you’re using Windows Defender Firewall, you will find the solutions below. But, if you’re using some other third-party firewall, you will have to find its guide. Typically, most Firewalls have a similar process. So, just try this out:
- Open Control Panel. Use any of the methods available to you for your Windows OS. Use the search bar.

- Once done, click on OK to save the changes and restart the PC. It should fix the error.
3. Assign A Letter To The Drive
Was any of the drive without a letter? You can find it by accessing the Disk Management option. If there were any such drive, you would end up ruining the mapping process. Thus, it will pose the same problems that you’re facing right now.
Windows operating systems have improved significantly. It comes with Disk Management tools. This tool will help you solve this issue efficiently. Let’s have a look:
- Launch the Run utility (Windows key + R key on keyboard). Type: diskmgmt.msc and hit Enter on your keyboard.
- Go to the partition, which doesn’t have a Drive Letter. Right-click on it and select ‘Change Drive Letter And Paths.’
- Now, click on the Add button and select a drive letter, or create one. Whichever suits you. Then, click OK.
- Don’t use A or B letters. They are for other drives.
- You will have to use this method on the system which doesn’t have a drive with a letter.
4. Try The Registry Editor
Alright, you haven’t had any luck so far. Now, this calls for desperate measures. The error of the local device name is already in use can be fixed with the registry editor.
For this, you will first have to back up the registry. Why? Because registry data, and the keys, are integral to the Windows operating system. They may not consume so much space, but their values keep your entire PC intact.
But, this doesn’t mean that you should invest in third-party registry cleaners. There is an entire market standing on helping in cleaning the registry. This does nothing, even if the claims are that it boosts your PC speed.
If there were any benefits or use to it, Microsoft would’ve launched their registry cleaner by now. After all, it has launched several other essential tools for us.
So, if Microsoft isn’t providing it, there’s no need for you to try it. This being said, Registry Editor isn’t that challenging to edit. As long as you modify or delete the keys that are posing problems, you will be fine. For this, you first have to backup:
- Go to the Search bar and type Registry. This should pop up the Registry Editor. Launch it.
- In the left panel, click on the ‘Computer’ option and then Export in the Menu. Now, this is your registry backup file. So you can name it whatever you’d like. Save it somewhere you will have an easy time finding.
- You can also export specific (individual) key values if you want to back them up before trying.
After the backup, it is time for you to deal with the key. The key name is MountPoints2.
- Once again, launch the Registry Editor if you don’t have it open already.
- Go to the following address: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
- Now, find the ‘MountPoints2’ in the list of the keys. Right-click on it and select Delete. That’s all you have to do.
Now, restart the PC and see if this solves the entire device name error or not.
5. Check For The Disk Space
As mentioned earlier, a lack of disk space could cause this error. You might have to check the network server computer for it. So, make sure to check for the space.
If you’re running low on the Network Server Computer, use your root drive. Your root drive can provide the extra space the server might need to operate.
There’s no exact value available. So, you just have to keep a couple of GBs empty, at least. You can do it by deleting unnecessary data. Transferring and storing data somewhere else also works just fine.
6. Restart The Computer Browser
The computer browser service is integral for the Network and Sharing Center. If you want to access other systems and vice-versa, you need to have this service. So, if you’re running into a problem accessing the network drive, it could be due to a computer browser. Thus, you can try this solution.
For many uses, this solution worked perfectly. So, give it a go:
- Launch the Command Prompt as Admin. Make sure to press yes at the prompt once it launches. You can use any method, either run, right-clicking Windows Icon, or anything else that you know.
- Now, all you need to do is make sure that you have a System32 command line. If so, type: net stop “Computer Browser.”
- Hit enter after typing that and wait for a couple of seconds while the command takes place.
- After that, type: net start “Computer Browser.”
- Hit enter, and this will restart the Computer Browser.
Now go ahead and access your mapped drive. See if the error persists.
7. Change The ProtectionMode Value
Once again, you’re back to a solution related to Registry. This was for when none of the fixes worked to solve the Network Driver issue. It is time for you to change the value of ProtectionMode.
Typically, the ProtectionMode activates when someone without permissions (Admin permission) tries to update. The system goes into protection mode. This could hinder any connection attempts. Thus, you can give these steps a try:
- Once again, open the Registry Editor. You can simply use the Run option and type ‘regedit’ then press Shift + Enter to launch it as Admin.
- After that, go to the following directory: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SessionManager\
- It is the path of the registry you need to work with. Now, find the ‘ProtectionMode’ key in the options you get.
- Double click on it and change the value from 0 to 1, or vice-versa. Then save and exit.
- Don’t forget to restart the system. See if this helps you solve the issue.
Also, much like the previous point, don’t forget to backup the registry. Do it before you make any changes, or even browse the Registry Editor.
