|Message:||NLB Cluster %2 %1: This cluster has left a bi-directional affinity (BDA) team in which it was the designated master. If other adapters are still participating in the team, the team will be marked inactive and will remain inactive until a master for the team is designated and consistent BDA teaming configuration is detected. %3 %4|
A bidirectional affinity (BDA) team is a set of adapters on a single host that act in concert. One adapter on each cluster host must be the master for that team. This event is logged when the master has just left the BDA team and a new master must be configured for the team to operate. Note that this can be a transient condition caused by a re-configuration of BDA teaming.
If this event is followed by an NLB 61 event in Event Viewer, no user action is required.
If this event is not followed by an NLB 61 event, then you need to change your BDA configuration. BDA configuration is specified by the Microsoft Internet Security and Acceleration Server (ISA Server) setup. For more information about configuring BDA, see the relevant ISA Server documentation.
