I have a file server that was upgraded to Server 2016. The upgrade went well, no errors during the upgrade. The odd part is the domain usernames in the share properties and security tab property's only show SID's. I can remove the SID and put the user from AD back as it belongs and it works fine. The even odder part is I can close the properties box and reopen it and the SID has returned! The users are still able to get to their files, no issues there but from an administrative stand point I the human cant translate a SID to a username.
Any help would be appreciative.
