I'm having problems being authenticated on the network after using RAS to
connect from my home computer. On my computer at home, the computer name is
\\HOME and my user name is greg. When I start RAS from home and contact the
office I can logon as Administrator, Greg, or Guest and all three give me an
Access Denied message when I try to access a share on the office computer. The
office computer name is \\GREG. The three above user accounts all exist on
the \\GREG computer which is running RAS Administrator. Why am I getting this
message?
ANSWER:
What is happening is that after logging into your local computer, your local credentials are being cached and used when you are trying to access your network. The RAS authentication does not override your cached credentials. Follow the steps below for explanation.
What's Happening:
1. You logon locally to your computer at home. Your computer name is home,
your user name is greg, and your password is password. (ex. \\HOME\greg
password)
2. Using RAS, you dial into your corporate network. An authentication dialog
box appears and you supply your RAS logon credentials. Your domain name is
corp, your user name on the domain is greg, and your password is
password. (ex. \\CORP\greg password)
3. The connection succeeds and you then try to connect to a computer in the
domain, for example, your office computer \\GREG. This is where you get an
Access Denied message.
Why:
The reason is that in step two above, your RAS logon does not log you onto the
network. It only verifies that you are allowed physical access to the
network. Therefore, here is the situation: You are logged on locally as
\\HOME\greg password. These credentials are cached and used for all resource
access locally and on the network. When you dialed into the network using RAS,
your cached creditials did not change. Therefore, when you try to connect to a
resource on the network, you give it: \\HOME\greg password and it is expecting
\\CORP\greg password.
Two Possible Solutions:
1. In step three above, when you are tying to connect to a computer on the
network, provide your network creditials to override your local
creditials. For example, at a DOS prompt, you would type NET USE *
\\GREG\PUBLIC /U:CORP\GREG. Or, in File Manager, in the Network Connect
Drive dialog box, you would type CORP\GREG in the Connect As box.
2. You can join the domain from home. This causes your domain creditials to
be cached on your home computer. To do this, have an Administrator add the
name of your computer at home, \\HOME, to the domain and change your
workgroup or domain name to corp. Then, follow the steps described in the
