Windows NT Server 4.0 pay-per-incident and hotfix support was scheduled to end on December 31, 2003.  However, based on feedback from our customers, Microsoft has made a decision to continue Windows NT Server 4.0 pay-per-incident and security hotfix support through December 31, 2004. Support for non-security hotfixes will not be extended.   Non-Security hotfix support ends December 31, 2003.    For additional information on the Microsoft Support Lifecycle for Windows NT Server 4.0, or any other product, please see http://support.microsoft.com/lifecycle.  

Interesting...I know there are a LOT of NT 4.0 Servers out there...looks like NT 4 will be with us a while longer.
