Why not create a limited users group and policy and then add users to and from as needed.

Yes you will have to have them on the domain....I am not sure what the issue is adding them to the domain??

But it would make them easier as a whole to manage....instead of individually.

If you are worried about your network...dont let them "physically" plug into it....whether they are on your domain or not.

I guess you can try and publish a shared folder on the server with everyone full access....and then have them connect via the IP address of the server using a unc path

\\ipaddress\sharename

Not sure that will work....cause I have no open shares like that.....and the only people that can access resources are "authenticated users"

Are they going to be running an application....cause you may need some server resources that will not be available using an open share.
