Hi.

Is it possible, using Windows XP Pro security mechanisms, to
authenticate access to a shared folder using BOTH machine and user
credentials?

i.e., userX can only login from machineX, not machineY. userY can only
login from machineY or machineX, but not from any other machine.

If so, how?

If not, why not? Any suggestions for how I could accomplish similar goals?

Thank you much,

Jacob Killian

No. Access to a share is made in the security context of the
account making the access. What you can do is control what
machines can communicate with the serving machine (without
regard to user at the time), and then of course use normal
permissions for the user access. That however cannot address
the scenario you outline.

Roger,

Thank you for your prompt response. Unfortunately, in my situation, all
clients need access to the server, however, I wish to be able to have
more granular control over who, what, when, where than seems to be
available through XP.

Do you have any idea if Vista will offer more granular access control?

Thanks again,
Jacob

I have seen no change toward allowing Windows to provide built-in
the type of access you are after. It is not an issue of being more granular
but of adopting an entirely different access control model. Access is gated
based on the credentials in use for the access, and the machine where a
domain principal is logged in is not part of the identity of those
credentials.
I have not looked in detail at how right management wares address this,
but I believe such are quite able to do what you outline.
