Hi,
I have threes sites with different networks connected to each other by a firewall (Cisco Firewall) in each site and doing NAT.
During the process of creating cluster, we can't add the other two servers in the other networks to the created cluster in first site.
the error message (This operation returned because the timeout period expired) and it is hanging for while when adding node from different network on the following phase (waiting for notification that node is a fully functional member) and then takes 3 minutes and failed to add any node from the other two networks.
All servers have Windows Server 20s08 R2 with SP1, Windows firewall disabled on all nodes and doesn't have any Antivirus or third party software firewall.
Each site has a CISCO firewall device.
Please we need to solve this issue and your help and recommendations are appreciated.
Thanks.
