When applied to a computer running an Active Roles client application, such as the Active Roles console, Web Interface or ADSI Provider, this setting determines the instances of the Active Roles Administration Service to which the client application is not allowed to auto-connect. This setting only affects the Administration Service instances that are published by Active Roles for auto-discovery.
If you enable this setting, you can specify a list of computer names identifying the computers running the Administration Service to which the client application is not allowed to auto-connect. In a computer name, you may use an asterisk wildcard character (*) to represent any string of characters. If a given computer is listed in this setting, then the client application is not allowed to auto-connect to the Administration Service on that computer unless the name or alias of that computer is listed in the Allowed Servers for Auto-connect or Additional Servers for Auto-connect setting.
If this setting is disabled or not configured, the client application normally auto-connects to any available Administration Service that is published by Active Roles for auto-discovery. However, you can use the Allowed Servers for Auto-connect and Additional Servers for Auto-connect settings to specify explicitly the instances of the Administration Service to which the client application should auto-connect.
