I want to share a encrpyted file (EFS), i am using XP SP 2 and on a workgroup.
I have the certifate of the other user and have installed it on my laptop but when i go to add the users certifate to the file the
add user us greyed out. Unlike when you are on a domain you can just select the user.

I am thinking that is just not a option but if anyone know how it would be a great help.
