hello all,
thanks for the time. i am configuring a 2node dhcp hot standby failover. the problem is that i can get a couple of scopes to be configured for failover but then after a bit it loses connections. and then picks up communication. and then fails. this is constant in the event logs. i have removed the partnerships and tried a few times... but same results. i can telnet from dc01 to dc02 on port 647. should i add a firewall excpetion for it? below are the logs. any help, suggestion, thought is appreciated.
