Hi Guys,
I've a strange and mysterious Traffic dropping all the network caused by one of the HUB\CAS servers.
We have Exchange 2010 Environment 2 DAG Members and 2 HUB\CAS Servers we are using WNLB as a load-balancing Solution.
We have two physical hosts and we virtualized the all servers mailbox and HUB\CAS
MBX-01 -- HUB-CAS-01 on HV1
MBX-02 -- HUB-CAS-02 on HV2
When Both servers are up strange traffic begin and all telephony system "Avaia" go down.
I've disabled the replication on the MAPI network on both DAG members to ensure that the replication traffic goes throw the private network and changed the mode of NLB " Multicast and then Unicast" and nothing changed any ideas.
All servers running Exchange 2010 SP3.
Thanks
Best Regards
Mohamed Attia
