I have about ~30 workstations that I administer, plus a fileserver, all of which I inherited when I took this net admin job. The previous guy had been around forever from when the company was far smaller and just put up with the hassle of dealing with it as a workgroup. Now we have a remote location and far too may users and workstations to make this feasible.
Currently the users have a username/password on their workstation, and a matching one on the fileserver. There are local groups set up on said fileserver so that the people in various departments have the correct access to the folders they need.
Shortly I'll be making the fileserver into an active-directory server as well and migrating everything over to a domain so I can centrally administrate everything. I'm wondering if there's a way to copy/migrate the local groups over into the domain groups so that I don't have to go recreate the same permission structure for the shares. I'll be changing the username schema, but definitely would like to be able to keep the groups if possible.
