The ALB team that is unable to communicate is attached to an external HyperV Network.
Updated: Remvoing the HyperV network allows the adapter to communicate on that Team Again.
Further update to this, using VMLB on this Team resolves all communication issues effecting the ALB team.
VMLB teams would be the best choice for load balancing and fault tolerance. The VMLB teaming mode was developed specifically to take the place of the AFT and ALB modes when using Hyper-V.
You mentioned in your first post that you had issues with the VMLB teams. Are you saying that with after moving to 15.5 the VMLB teams all work correctly? Let us know if you still have any issues.
