We have a client who we added 4 new domain computers to over the weekend (they had an existing 6 on the domain) to an existing domain control virtual machine running Windows 2012 Standard R2. Ever since the users started working on Monday the files on the server and network shares are opening as "Read-Only". We've checked the shares and they are set to Full Access, we've checked subfolders and they have full access and aren't locked for read only. We have checked for files being open on different workstations causing the issue and all files are closed. This issue did not exist before adding these users and the issue is being experienced by all users (all on Windows 10 pro), those who were on the domain before as well as new users.
