Thanks to Sean Rima for the tip: Microsoft has released two new post-SP3 hot-fixes for Windows NT 4.0. The first, "LSA secrets fix", prevents local Administrators from displaying the contents of security information stored by the Local Security Authority (LSA) in a form called LSA Secrets. LSA Secrets are used to store information such as the passwords for service accounts used to start services under an account other than local System (Basically this program available allows anyone to view the LSAs). This hot-fix is available on the Microsoft FTP site.
The second hot-fix, "NetBT fix", fixes a problem that causes initial dial-in attempts on a remote sight to take up to 90 seconds to complete. This fix is also available on the Microsoft FTP site
