RE: Log on the domain

[<marc () saharadigital com>]

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 :)

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.

  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.)
