At a loss on this one.
I have a 2003 server in a work-group that host old applications. Users run EXE through a UNC or mapped drives. Groups and users were created on the server and matching on the PC side.
There is a separate office I have installed a 2012 server with Active Directory. These users still need access to those programs.
I joined a computer to the domain, logged in as the domain admin, mapped the drive as a work-group user and can pull up all apps. If I log in as a domain user I cannot access two of them.
Giving the “Everyone” group full permission to the folder
Gave the domain user local admin rights
Gave the domain user domain admin rights
I have checked and ensued the mapped drive is using the local account to map and the password is correct.
I cannot promote the server to a Domain Controller. Any other ideas would be appreciated.
