DNS request timed out. timeout was 2 seconds. _h323cs._tcp.xyz.com SRV service location: priority = 0 weight = 100 port = 1720 svr hostname = 192.168.1.252
the group 500 use the same dns server and the domain set xyz.com in the Lan properties.
when I set the gatekeeper to auto the registration fails. so I tried to capture the traffic using wireshark but it seems that the group series is not doing the SRV lookup, it is trying to sent a registration request to broadcast address 220.127.116.11 as below without receiving any response.
