Created a DAG for Exchange 2013 between two mailbox servers. Server 1 is main , Server 2 is connected via Cisco VPN client to Server 1 network. Trying to start the seeding process to create a backup copy of the mailbox to Server 2.
Get the following error:
The seeding operation failed. Error: An error occurred while performing the seed operation. Error: An error occurred while communicating with server 'Server 1'. Error: Cannot determine the frame size or a corrupted frame was received. [Database: Mailbox Database 2143525880, Server: Server2.domain.local]
tried modifying the network adapter parameters. Jumbo frame, RX limit, TCP offload etc.
but nothing worked
Server 1 is Windows VM running on VirtualBox behind a Cisco ASA firewall Server 2 is windows VM running on VMWare connected to Cisco ASA via Cisco VPN client.
Server 1 and Server 2 can ping each other, access each others resources. No firewall rules blocking traffic between VPN network and internal LAN.
Any ideas on where to look would be really appreciated
