    More than a dozen people contacted me requesting the useful online references for customizing security templates ... so here they are:

    Security Configuration Manager overview (includes critical info about how you can use it on NT4)
    http://support.microsoft.com/search/preview.aspx?scid=kb;en-us;Q245216

    SDDL (security descriptor definition language) reference:
    http://msdn.microsoft.com/library/en-us/security/Security/security_descriptor_definition_language.asp

    This SDDL reference is pretty ugly IMO, so I wrote a summary of the important info (adding helpful info I found in "Inside Active Directory" by Kouti & Seitsonen) which you can find in the appendix of this document:
    http://windows.stanford.edu/docs/ADSecurityOverview.htm

    How to Add Custom Registry Settings to Security Configuration Editor
    http://support.microsoft.com/default.aspx?scid=kb;EN-US;q214752

    How to add multiple multi_sz values using an .inf file
    http://support.microsoft.com/search/preview.aspx?scid=kb;en-us;Q322083
