Adding and removing users from the Windows groups
On Windows systems, the two groups <grid-name>_full and <grid-name>_read determine which users have full access or read access, respectively, to the grid folder structure. If other users than those that are assigned to the groups at install time need access, they should be added to these groups.
Note: Group membership is resolved at logon, so in order for the changed group membership to take effect, any affected users need to log out and log on again.
