node 'mail02' failed join cluster because not send , receive failure detection network messages other cluster nodes. please run validate configuration wizard ensure network settings. verify windows firewall 'failover clusters' rules.

if @ cluster log files, same error.

event 1572: node 'mail02' failed join cluster because not send , receive failure detection network messages other cluster nodes. please run validate configuration wizard ensure network settings. verify windows firewall 'failover clusters' rules.

i ran cluster validation check networking between 2 nodes , get.

the hostrecordttl property network name 'name: dag' set 300 ( 5 minutes). local clusters suggested value 1200 (20 minutes).

for this, run following command. “cluster res "cluster network 1" /priv hostrecordttl=1200” keep getting error 5007, cluster resource not found. not sure why getting error since “cluster network 1” correct name.

i getting message in validation.

node mail01.domain.local reachable node mail02.domain.local 1 pair of interfaces. possible network path single point of failure communication within cluster. please verify single path highly available or consider adding additional networks cluster. following pings attempted network interfaces on node mail02.domain.local network interfaces on node mail01.domain.local.

success  192.168.50.15  192.168.150.15

it seems obvious issue related network, can’t figure out what. windows firewall turned off on both servers. created service object udp 3343 in both sonicwall routers. ip address of mail01 192.168.150.15 , mail02 192.168.50.15. missing?

wow, incredibly easy do. removed dag , cluster. instead of creating dag first automatically creates cluster, created cluster first. created cluster adding both nodes , setting quorum witness server. when went create dag, got error dag account enabled. easy enough, went ad , disabled account. went exchange , created dag. re-enabled ad account , added both servers dag.
