1 out of 2 DNS servers is down
| Posted by Tomcatf14, 05-21-2008, 01:17 PM | | There are few clients complaining site inaccessible but it could be accessible from other location.
Does this mean that the client's is resolving to the down DNS server? Any fix on this to force the client to resolve to the main DNS server?

| Posted by Tomcatf14, 05-21-2008, 02:12 PM | | Positive one is down. I can access the primary but not the secondary. Primary is holding the same records as secondary. I believe my client is using a DNS server (ISP) that queried the secondary DNS and i am using a DNS server that queried the primary DNS server. Please correct me if I'm wrong.
nslookup domain.com ns1.myhost.com = is OK
nslookup domain.com ns2.myhost.com = Not reachable
nslookup domain.com ns1.ISP.com = Not OK
nslookup domain.com ns1.otherISP.com = OK

nslookup domain.com ns1.myhost.com = is OK
nslookup domain.com ns2.myhost.com = is OK
nslookup domain.com ns1.ISP.com = is OK
nslookup domain.com ns1.otherISP.com = is OK
