RRAS agent
VPN technology can be implemented through the 'Microsoft Routing and Remote Access Service' (RRAS) provided with every Windows Server operating system. UserLock can audit, control and restrict VPN sessions on this RRAS architecture by deploying its 'RRAS agent' designed to be loaded in the Microsoft RRAS service.
UserLock doesn't deploy this specific agent automatically. It needs to be deployed manually through the console or by file copy.
