Restrict access to my computer

[Thomas]

Hi everyone!

In my school we have a pretty huge network, for which I'd
like to make sure that not everyone has complete access
to my shared folders.
How do I make an authentication screen show up on every
computer that wants to access mine, so that the person
trying to gain access has to authenticate himself with a
username and password assigned by me?

Thanks for your help in advance!

Thomas,

What operating system do you have on your computer? You can provide
authenticated access with Windows XP Pro, or Windows 2000. You can't provide
authenticated access with XP Home.

Sorry for the lack of information, I'm running on Windows
XP Pro.

OK, Thomas,

On XP Pro, disable Simple File Sharing (Control Panel - Folder Options - View -
Advanced settings - last entry in the list)

With XP Pro, if SFS is disabled, check the Local Security Policy (Control Panel
- Administrative Tools). Under Local Policies - Security Options, look at
"Network access: Sharing and security model", and ensure it's set to "Classic -
local users authenticate as themselves".

Then setup userids with strong passwords. Should do it.

If the school network is set up as a domain, consult with the network
administrator on how to do what you want. The domain controller, not
your computer, will handle user authorization.

If the school network is set up as a workgroup, the solution depends
on what version of Windows XP your computer has.

If it has Windows XP Professional, disable simple file sharing and set
up access control on your shared folders. Ron Lowe and I have written
a web page with full details:

Windows XP Professional File Sharing
http://www.practicallynetworked.com/sharing/xp_filesharing/index.htm

If it has Windows XP Home Edition, access control lists aren't
available. Instead, assign a network password to the Guest account.
Other people who want to access your computer will have to provide
that password:

1. Click Start | Run.
2. Type "control userpasswords2" in the box and click OK:
3. Click Guest.
4. Click Reset Password.
5. Enter and confirm the password.

Thank you very much for your fast responses!
I carfully followed your instructions, but it somehow
doesn't work. People can still see my shared folders, the
only difference is that when they try to access one, they
are issued the error message that they are not allowed to
access the directory. There is not authentication dialog,
just that error message.

Any help would be greatly appreciated!

Thomas,

OK, I think I see your question now.

If you're using Advanced File Sharing under Windows XP Pro (Simple File Sharing
disabled), the account / password used (from your friends computer) has to match
the account / password setup on your computer.

You setup an account / password on your computer. Your friend then has to Map a
Network Drive to your computer, and select "Connect using a different user
name". That will popup an authentication dialogue, where he / she can enter the
account / password that you setup.
