User Groups and Access Permissions

RTX64 provides several Windows user groups to allow for granular control of RTX64 permissions.

Group	Permissions
RTX64Administrators	Full access to all RTX64 resources, including the ability to debug RTSS applications
RTX64Users	Read access to all RTX64 resources Ability to execute RTSS applications Ability to debug RTSS applications Ability to terminate RTSS processes See Notes below.
Windows Administrator	Boot configuration Windows Idle State configuration Device conversion

By default, all authenticated users who log on to the system can control, configure, and run the RTX64 Subsystem and RTSS applications. The default RTX64 groups include:

• The Windows group Authenticated Users
• The Windows user SYSTEM (also known as LocalSystem)

System administrators can control access to the RTX64 resources by configuring members of the RTX64Administrators and RTX64Users groups.

IMPORTANT! The Windows user SYSTEM must never be removed from an RTX64 group.

When modifying RTX64 groups, remove Authenticated Users from all RTX64 groups, then add individual users to specific groups based on their usage needs.

Notes

• For a member of RTX64Users to perform the actions listed in the table above, one of the following scenarios is required:
• Someone with greater permissions must first start the Subsystem for them. Or,
• The RTX64Users member must elevate, via Administrator Command Prompt, the application they wish to run or terminate.
• Members of RTX64Users cannot stop the RT-TCP/IP Stack.
• Only one instance of the RTX64 Control Panel can be opened in a session. For example, if a member of RTX64Administrators has opened the Control Panel, a member of RTX64Users cannot open another instance of the Control Panel.
• When you make a change to any of the three RTX64 groups above, you must log out and then log back in for the change to take effect.
• If you encounter an error while attempting an operation, check your RTX64 group membership.
