Hi,
i recently shifted my zone from MS server to infoblox there is some observation that whenever i do nslookup it gives me 2 X time out for every query and than resolve also for the query for which my server is authoratitive.
when i switch back to MS or on my bind it is OK.
I understnad that some time nslookup is not recomended but if this happen on Infoblox it must happen on other platform.
right now i cannot install dig utility to test .
Any body have clue is there anything i am missing.

 

Thanks

Greetings!

Let me start with a couple of simple questions.

1. Do you have both v4 and v6 enabled on this Windows client? You can confirm this by navigating to ncpa.cpl-->Ethernet Properties

2. This could be because of DNS suffixes. You can confirm this by navigating to ncpa.cpl-->Ethernet Properties-->Ipv4 Properties-->Advanced-->DNS-->Append these DNS suffixes.

To workaround suffixes in nslookup you can perform the query with a period in the end. (www.example.com. instead of www.example.com)

3. If you run 'nslookup' in the following fashion, do you experience the same problem?

nslookup
server 10.X.X.X  // Specify your authoritative IB DNS server
set q=a  // This specifies that you are querying for an 'A' record
www.example.com  // Your DNS A record query FQDN
