I have a small client with one server, recently upgraded from SBS2003 to SBS2011, and 5 Windows 7 workstations. For reasons unknown to me, the previous IT guy setup all of the workstations on a workgroup rather than the domain. They also set all of the local and domain usernames/passwords the same to make connecting to network resources easy.
We're having an issue where after a user opens a document off the server, makes changes, and then saves the document, nobody can access the document until I reset the permissions, not even the last user to save it. If I login as a domain admin I can't even view the permissions or owner of the file, the owner says Unknown User, and I just have to take ownership and reset the file to inherit permissions.
I've never seen this happen, and it was not a problem on the old server, but I'm guessing it has to do with the non-domain computers not acknowledging the existing domain based permissions. If that makes sense? My inclination is to switch all of the workstations over to the domain, but I hate the whole user profile migration process and the downtime involved for each user. At least it's only 5 users though.
Has anyone else seen this issue? Do you have any suggestions for resolving it? Is it something specific to non-domain computers and server 2008/2011?
