Hello,
currently we are using two W2K12R2 DHCP server configured in "load balance Mode". On DHCP1 the IP-scope with failover partnership to DHCP2 is deactivated. DHCP2 is working fine. Now we register that 50 percent of our clients (W2K8R2 application server) losing the network connectivity for 3 sec. after rereleasing they IP-Address. On DHCP2 servers eventlog we receive a lot ofBINDING ACK reject events 20291 and 20292 for these IP addresses entries.These 3 sec. of loosing they Network connectivity is our big Problem because the Client application (W2K8R2 application server) cannot handle these timeout. It looks like aDISCOVER-OFFER-REQUEST-NAK cycle that are described here: http://blogs.technet.com/b/teamdhcp/archive/2014/02/26/dhcp-failover-patch-to-address-a-reservation-issue-and-another-issue-related-to-failover-partner-not-accepting-state-transition-from-bad-address-gt-active-has-been-released.aspx#pi47623=2
there is a solution to prevent the 3 sec network failure?
