Applies to: desktop apps only

The UnavailabilityTime property gets or sets the time, in minutes, during which a RADIUS server that failed to respond to retried requests will remain unavailable for subsequent requests.

This property is read/write.

Syntax

HRESULT put_UnavailabilityTime(
  VARIANT_BOOL lTime
);

HRESULT get_UnavailabilityTime(
  long *plTime
);

' Data type: Long

Property UnavailabilityTime( _
  ByVal lTime As VARIANT_BOOL, _
  ByVal plTime As long _
) As Long

Property value

A 32-bit integer that specifies the time, in minutes, during which a RADIUS server that failed to respond to retried requests will remain unavailable for subsequent requests.

Error codes

These property methods return S_OK if the call is successful; otherwise, they return an error code.

Remarks

This property is read/write. Its default value is 2 minutes.

This property is only used by application filters that call the IFWXRadiusAuthenticator::AuthenticateRadiusUser method to request RADIUS authentication. Specifically, the Forefront TMG Web proxy, which is implemented as an application filter, uses this method to request RADIUS authentication of its clients, and the availability of RADIUS servers for authentication is therefore affected by the value of this property. Conversely, this property does not influence the availability of RADIUS accounting and authentication for VPN clients.
