Unable to add MBX02 into DAG

Dears,

i am installing and configuring Exchange 2013, and now i want to add a second Mailbox server into DAG but i got the following error:

error

A server-side database availability group administrative operation failed. Error The operation failed. CreateCluster errors may result from incorrectly configured static addresses. Error: An error occurred while attempting a cluster operation. Error: Cluster API '"AddClusterNode() (MaxPercentage=100) failed with 0x5b4. Error: This operation returned because the timeout period expired"' failed.. [Server: MBX02]

i walked through the prestaging process with no luck. link: https://technet.microsoft.com/en-us/library/ff367878.aspx

i have disabled the IPV6 and all offloading functionality with no luck.

That can be caused by several things, the most common being that there isn't a DAG IP address that's on the same MAPI subnet as the computer you are installing.  It also can be caused by incorrectly defined subnets or network problems.

Folks, 

I figured it out, you need to disable the TCP checksum on the V-switch on hyper-V.

after that its like Magic.
