DescriptionNLB cluster [%2]: The bi-directional affinity (BDA) team in which this cluster participates has no designated master. The team is inactive and will remain inactive until a master for the team is designated and consistent BDA teaming configuration is detected.
Event InformationAccording to Microsoft :
Cause :
This event is logged when the bi-directional affinity (BDA) team in which this cluster participates has no designated master.
Resolution :
Reconfigure BDA teaming configuration
The bi-directional affinity (BDA) configuration must be identical on all cluster hosts. The team in which this cluster participates will be marked inactive and this cluster will remain in the converging state until consistent teaming configuration is achieved. You should first reconfigure the BDA configuration, and then restart the NLB cluster.
Reconfigure the bi-directional affinity configuration
To reconfigure the bi-directional affinity configuration:
Reconfigure the bi-directional affinity settings by using the server application tools. If the Network Load Balancing (NLB) cluster is an Internet Security and Acceleration Server (ISA Server) cluster, use the ISA Server configuration.
When you are using nlb.exe, you must be a member of the Administrators group on the host that you are configuring, or you must have been delegated the appropriate authority. If you are configuring a cluster or host by running nlb.exe from a computer that is not part of the cluster, you do not have to be a member of the Administrators group on that computer.

To restart the NLB cluster:
1.Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
2.Type nlb.exe reload, which reloads the NLB driver's current parameters from the registry.
3.Type nlb.exe start, which starts cluster operations on the specified hosts.
Verify :
The configuration of bi-directional affinity must be the same on all hosts in the Network Load Balancing (NLB) cluster.
To verify that the bi-directional affinity configuration is the same on all hosts:
1.Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
2.Type nlb.exe query. This displays the current cluster state and the list of host priorities for the current hosts of the cluster. Confirm that all hosts display converged as their current state.
