The 1722 error normally appears when your system tries to use the NetUserGetLocalGroup function. This function allows your computer to read data from other computers on your “local” network, but often gets confused with the permissions that your system has, making it impossible for your system to open the files it needs, causing the error. To fix this error, you basically need to enable the TCP/IP protocol and then clean out viruses & other errors from your system.

This error shows in this format:

A system error has occurred: 1722

In order to fix this error, you first need to be able to enable “NETBIOS” over TCP / IP. This basically allows your system to read more files & better control another system without causing any damage to it. This is disabled by default in the average Windows system, but if you enable it, it will allow your PC to read the various files it needs, preventing the 1722 error.

After you’ve done that, you should then look to use an antivirus program to scan through your PC and fix the various infections that your computer might have. Viruses often cause the 1722 error as they are continually corrupting your Internet settings. Any computer can get a virus, making it vital that you’re able to get rid of any potential infection by using a reliable antivirus program.

You should also use a ‘registry cleaner’ to scan through your system and repair any potentially damaged parts of your Windows system. The registry is a large database which stores vital settings & information that Windows requires to run, and is where your computer keeps everything from your Internet settings to your desktop wallpaper. Unfortunately, the registry is also one of the biggest causes of problems & errors, as it is continually being saved in the wrong way. To make sure this is not a problem, it’s recommended you use a registry cleaner to scan through your PC and fix the damaged registry settings that could be causing errors.
