I greatly value the knowledge that I've gained from this group and I love to be 
occasionally be able to give back. At the risk of making this seem too easy, here is 
the exact "google query" that I used: "site:support.microsoft.com 
RestrictAnonymousSAM" (without the quotes)

I love the "site:" modifier

May the google be with you <g>

Your google-fu appears to be very strong young one...

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\RestrictAnonymou
s 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?
