The locally-administered configuration file is referenced in the registry as HKEY_LOCAL_MACHINE\Software\WALLDATA\ConfigFile
The configuration files exist so users can provide their configuration preferences within the communications environment.
The system-administered configuration file is referenced in the registry key as HKEY_LOCAL_MACHINE\Software\WALLDATA\Sna\AdminOverrideConfigFile.
You can use the administrator override configuration file as a set of configuration elements that will override all other configurations. Any configuration element you specify within AdminOverride-ConfigFile will then take precedence over the corresponding element contained in ConfigFile. This means that if collisions occur between the elements of the ConfigFile and AdminOverrideConfigFile, the winner will be the AdminOverrideConfigFile.
For example: if ConfigFile contains an MPTN link definition named NETRED and AdminOverrideConfigFile contains an SDLC link definition named NETRED, then AdminOverrideConfigFile’s SDLC link definition will replace the ConfigFile’s MPTN link definition.
