Ok guys, Real simple: Make the following Reg entries on the Workstations: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon] "cachedlogonscount"="0" Now if you do not have a "local" account on the workstation no DC authentication = no logon. You should add these others too. "PowerdownAfterShutdown"="0" "ShutdownWithoutLogon"="0" "AutoAdminLogon"="0" "ForceUnlockLogon"=dword:00000001 "DontDisplayLastuserName"="1" "ScreenSaverGracePeriod"="0" _____________________ Dave Kleiman dave () netmedic net www.netmedic.net -----Original Message----- From: marc () saharadigital com [mailto:marc () saharadigital com] Sent: Thursday, April 17, 2003 12:19 To: mwharbi () hotmail com; security-basics () securityfocus com Subject: RE: Log on the domain forgive if this is incorrect but it's been a while since I've done this. If you only have the Local administrator as a local user and delete the local administrator profile (as well as any other local profiles if they exist) when you logon, you shouldn't even have an option to select a local logon. If no domain access is available you will still be able to logon using cached credentials/profiles which was a problem in NT4. I'm sure others can verify as I'm not at a machine at the moment where I can test it to make sure. I've done this before so I know it can be done and I at least know I'm on the right track :) -----Original Message----- From: Rusty Morgan [mailto:RMorgan () mbaj com] Sent: Wednesday, April 16, 2003 7:48 AM To: gillettdavid () fhda edu; J.S; security-basics () securityfocus com Subject: RE: Log on the domain David, I think you are correct about the log on locally issue. Meaning that it controls whether they can log into the console of the server. Regarding JS's issue I have not been able to find a policy or setting that will do what you want in NT/2000. As someone mentioned previously in Win98 you can use the Policy Editor to force a domain login. They also mentioned that it was not a foolproof method for keeping them out. To keep my users from logging in locally I don't create any local accounts and the admin password it unknown to them. That password could always be cracked, but overall this seems to be the easiest way to accomplish what you want.

-----Original Message----- From: J.S [mailto:mwharbi () hotmail com] To: security-basics () securityfocus com How can we enforce the users log on to domain? I mean: Users can not access computer using admin or any other account, must log on the domain controller. Is there any policy to do that?
I've always interpreted the "Log on locally" policy as determining whether a given user account can be used from the "console" keyboard and monitor; i.e., an account without this right can only be used to access the machine remotely. I may have misunderstood that, since multiple people seem to think it's what you want. I don't think there is a way to lock out all local access. But with Windows 2000 policies, you *can* prevent them from accessing any network resources that are part of your domain structure. Is that good enough? (With NT domains, they can have access if their local account name and password matches a domain account and password that has access.)
