Remember my "I'm getting hammered with brute-force attacks as if 'Do not allow 
enumeration of SAM' setting wasn't there even though it is" problem?

Found the solution today.

Remember the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\LSA\RestrictAnonymous 
key in 2000, that you needed to set to "2" to do any good?

Seems that's been deprecated in 2003, and the new correct value is split into 2 
registry keys:

..\RestrictAnonymous=1
..\RestrictAnonymousSAM=1

Now, I've obviously only done this on my network, but I can tell you that a setting of 
"2" in ..\RestrictAnonymous had me wide open and getting hammered by account 
enumeration attacks, whereas changing it to a "1" now has my IPC$ share behaving the 
way I thought it should've been.

The kicker?  I can't find any mention of the change in an MS Article (though Deji or 
someone will doubtless prove me wrong in about 5 seconds with their superior Google-fu 
skills :-)).  And the Windows Server 2003 Deployment Kit actually references "2" as a 
valid entry for ..\RestrictAnonymous.

Can anyone confirm or deny this before I go making a fool out of myself by submitting 
an incorrect or redundant KB article?
