Thanks Alexander for this update. HFNetChk is a command-line tool that enables an administrator to check the patch status of Windows NT 4.0, Windows 2000, and Windows XP machines.
HFNetChk can be run from Windows NT 4.0, Windows 2000, or Windows XP systems, and will scan either the local system or remote ones for patches available for the following products: Windows NT 4.0, Windows 2000, Internet Information Server 4.0 and 5.0, SQL Server 7.0 and 2000 (including Microsoft Data Engine), and Internet Explorer 5.01 and later.
(HFNetChk will NOT operate on Windows 95, Windows 98, or Windows ME systems.)
