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

This error is displayed in this format:

A system error has occurred: 1722

To fix this error, you must first be able to enable “NETBIOS” over TCP/IP. Basically, this allows your system to read more files and better control another system without causing any damage to it. This is disabled by default on the average Windows system, but enabling it will allow your PC to read the various files it needs, avoiding the 1722 error.

Once you’ve done that, you should look into using an antivirus program to scan through your PC and fix any various infections your computer might have. Viruses often cause the 1722 error as they continually corrupt your Internet settings. Any computer can have a virus, so it is vital that you are 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 that stores vital settings and information that Windows requires to run, and it’s where your computer saves everything from Internet settings to your desktop wallpaper. Unfortunately, the registry is also one of the biggest causes of problems and errors as it is continually being saved incorrectly. To make sure this isn’t a problem, it’s recommended that you use a registry cleaner to scan through your PC and fix any corrupted registry settings that could be causing errors.
