Microsoft Error Code 1722

Errors in Microsoft Windows are often cryptic, with numbers being the only clue to their meaning.

Error code 1722 affects Windows XP, 2003, and 2000. It is difficult to diagnose because it is associated with multiple problems that occur in Windows.

Occurrences

Error code 1722 appears when NetBIOS is disabled over the TCP/IP connection. The attempt to access this feature occurs whenever an application uses the NetUserGetLocalGroup function unsuccessfully.

Resolution

A missing update is the primary cause of the error code. If you're using Microsoft Windows 2003, you need to install service pack 1. If you're using Windows 2000, you need to download the Windows Server 2000 Service Pack (SP4) Rollup 1.

Workaround

If the update is not available, it's also possible to use a workaround to enable the service. In the "Control Panel," locate "Network Connections" followed by "Internet Connections." Click "Local Area Connections" followed by "Properties." Select "TCP/IP" and then "Properties." Go to "Advanced" and locate the "WINS" tab. Locate "Enable NetBIOS over TCP/IP" and select "OK."

Additional Errors

This error is also found when installing a corrupted version of the Javascript installer. Remedy this by locating an alternative download location.
