Reason for Revision:

Microsoft originally released this security bulletin on March 17, 2003. At that time, Microsoft was aware of a publicly available exploit that was being used to attack Windows 2000 Servers running IIS 5.0. The attack vector in this case was WebDAV although the underlying vulnerability was in a core operating system component, ntdll.dll. Microsoft issued a patch to protect Windows 2000 customers shortly afterwards, but also continued to investigate the underlying vulnerability. Windows NT 4.0 also contains the underlying vulnerability in ntdll.dll, however it does not support WebDAV and therefore the known exploit was not effective against Windows NT 4.0. Microsoft has now released a patch for Windows NT 4.0.
