Login to Domain Without Being Connected to Domain

Posted on 2005-04-25

I have a laptop that on which I logon to a Domain at work (large network). I do not have any local user defined on the laptop, only a domain user id (domain\user).

When I take the laptop home, I can log into the laptop with the domain user Id, even though I am not connected to the Domain.
(Of course I have no access to Domain resources at this point).

Question 1: How am I able to log into the Laptop with a domain user ID even though I am not connected to the Domain?

Then, I use a VPN connection to connect to the Domain, and I receive a Login greeting and have full access to Domain resource.

Question 2: How is a Login Script launched when I am not logging in (again). The only time I logged in was when disconnected from the Domain.

    You are utlizing what is known as windows cached credentials.

    Windows remembers the last 10 logons for your computer and caches this information. So you logon to the domain at work...unplug and go home....then when you log on then you are using cached credentials.  This is for obvious that you don't have to have a local account when you are away from your domain.  If this behavior is not desirable then you can change windows to not cache any logons.

    As for question 2....not sure how your vpn is setup...but since you are using cached credentials to logon to the laptop then the login script must be iniated when you connect via VPN and somehow you are actually authenticating with the domain thru the would have to be for the logon script to work. Your system admin would be able to give you a better explanation as he/she will know the details of your network.
