Here are all possible troubleshooting methods to fix this system error.

If system error 1231 has occurred, then before doing anything and trying various methods, one quick solution to resolve error code 1231 is to simply switch the network. Or you can also use mobile hotspot. If the problem persists, try the methods below.
Method 2: Change PC name
When setting up Windows during installation, it asks you to enter a name for your PC. If you used any lowercase letters in it, then the problem lies in the name itself and therefore system error 1231 occurred. Windows 10 made many changes to its system settings, including now it will not list a device in the workgroup if the device name is contains lowercase letters. To fix this, rename your device in capital letters. Do the following:
1. Press the Windows + I keys at the same time to open Settings.
2. Here, click "System Preferences".
3. Then click "About" and click "Rename this PC".
4. Enter a new name in capital letters only and click Next.
5. Click Restart Now.
Method 3: Troubleshoot your Internet connection
TCP/IP or Transmission Control Protocol/Internet Protocol is a data link protocol used to send and receive data and connect network devices, which basically allows two systems to connect and exchange data. Due to incorrect settings and configuration, connection problems between devices can occur. So, to fix this, try resetting TCP/IP. Do the following, read our TCP/IP reset guide.
Note. It is also recommended that you use this method on other computers that are connected to your workgroup network.
Method 4: Turn on network discovery
One of the main causes of error code 1231 has to do with incorrect network discovery settings. Clearly, remote computing is not possible unless the workgroup network is configured to be discoverable with automatic configuration disabled. Here's how to fix it by following these steps.
1. Press the Windows key, type Control Panel and click Open.
2. Change View by function to Large icons.
3. Click on the Network and Sharing Center menu.
4. Then click "Change advanced sharing options".
5. After that, in the "Private profile" section, click "Turn on network discovery" and select "Turn on automatic configuration of devices connected to the network."
6. Finally, click Save Changes.
Method 5: Run a virus scan
Viruses and malware usually change system settings and corrupt system files, and this is probably what causes system error 1231. To get rid of any virus or malware, perform a full scan using the built-in Windows scanner. Do the following, read our Guide to Running a Virus Scan.
Method 6: Reinstall the network adapter driver
The driver is a key component of the system, which is the link between hardware and software. If a driver is outdated or not compatible with a particular version of Windows, it will not be able to create a correct association between devices. To fix the error, first uninstall the driver so that it can be installed with the new setting. To uninstall and reinstall the driver, read our guide to uninstalling and reinstalling the driver.
Method 7: Create a new batch file
A batch file consists of scripts that can be executed by any command line interpreter to make multiple changes to a single batch file. So, if you don't want or can't change multiple device names to capital letters, you can try this instead by creating a new batch file. Follow these steps to resolve the issue with error code 1231.
1. Press the Windows key, type "Notepad" and click "Run as administrator".
2. Click Yes to give permission.
3. Paste the following text into Notepad.
sc.exe config lanmanworkstation depend= bowser/mrxsmb10/nsisc.exe config mrxsmb20 start= disabled
4. After entering the text, press the Ctrl + S keys at the same time to save the file.
5. Choose the location where you want to save the file and be sure to add the .bat extension after the file name. After that click Save.
6. Open File Explorer by pressing the Windows + E keys at the same time and navigate to the folder where you saved the batch file you just created.
7. Right-click it and select "Run as administrator".
8. Click Yes to give permission.
Method 8: Perform a System Restore
This method is really helpful when you can't identify the problem. The System Restore feature is like a time machine that will bring your system back to a point in time when it functioned normally without any errors. If you recently started encountering error code 1231, and there were no errors before, then you should perform the system restore process. Follow our guide to performing a system restore.
