As far as I can tell (I’m new at the company here, and I still haven't gotten a full run down of the environment) there will be people actually authenticating with them.   Brad Martin Go Daddy Software -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Leney, Justin Sent: Friday, December 27, 2002 12:13 PM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] Hardening Active Directory   Another setting that can have detrimental affects on down-level clients is the LAN Manager Authentication Level. Set it the highest level only if you will have Win2000/XP clients authenticating the domain.   The AD servers on the net; are they going to just support a web front end or something similar, or are users going to actually authenticate to them on a day to day basis?   -----Original Message----- From: Tim Hines [mailto:[EMAIL PROTECTED]] Sent: Friday, December 27, 2002 1:59 PM To: [EMAIL PROTECTED] Subject: Re: [ActiveDir] Hardening Active Directory I think that Gil is referring to the setting that sets "shut down the computer when the security audit log is full".  That caused servers to reboot over and over.  I also recall that one of the templates set additional restrictions for anonymous connections to "no access without explicit anonymous permissions".  This will kill downlevel trusts and keep downlevel clients from logging on.     Tim Hines, MCSA, MCSE (2000 & NT4) MVP - Active Directory         ----- Original Message ----- From: Larry A.
