Dear all,

I have installed a domain named active.msft with two domain controllers.
When I ping the name active.msft I received response 192.168.1.1 that is the
IP address of DC1. But after DC1 has been down, I repeat to ping active.msft
the response is still the same as 192.168.1.1 ,of couse it shows me "request
time out". Is this abnormal? By the way ,I have flushed the dns entry in the
client machine before second ping.

Any explanation will be appreciated.

Best Regard,

John Park
 
Check the NS records for the DNS zone corresponding to the domain. I suspect you have one NS record for DC1 and no NS record for DC2

Add a NS record for DC2 and then type 'nslookup active.msft' to retrieve a list of NS records for the domain/zone

Ensure that the DNS server used by the client can failover too, in case DC1 is the only defined DNS server on the client from which ping is being executed. Consider adding DC2 to the list of DNS servers used by the client
