Where does a DNS server look first to resolve a query?
Local DNS cache of client computer, then the hosts file on the local PC finally going to the assigned DNS servers the computer is pointing to
What do the DNS servers do with the information learned from the iterative queries?
An iterative name query is one in which a DNS client allows the DNS server to return the best answer it can give based on its cache or zone data. If the queried DNS server does not have an exact match for the queried name, the best possible information it can return is a referral (that is, a pointer to a DNS server authoritative for a lower level of the domain namespace). The DNS client can then query the DNS server for which it obtained a referral. It continues this process until it locates a DNS server that is authoritative for the queried name, or until an error or time-out condition is met.This process is sometimes referred to as "walking the tree," and this type of query is typically initiated by a DNS server that attempts to resolve a recursive name query for a DNS client.

What does Disable Recursion in DNS mean?
HiIn the Windows 2000/2003 DNS console (dnsmgmt.msc), under a server's Properties -> Forwarders tab is the setting Do not use recursion for this domain. On the Advanced tab you will find the confusingly similar option Disable recursion (also disables forwarders). Recursion refers to the action of a DNS server querying additional DNS servers (e.g. local ISP DNS or the root DNS servers) to resolve queries that it cannot resolve from its own database. So what is the difference between these settings? The DNS server will attempt to resolve the name locally, then will forward requests to any DNS servers specified as forwarders. If Do not use recursion for this domain is enabled, the DNS server will pass the query on to forwarders, but will not recursively query any other DNS servers (e.g. external DNS servers) if the forwarders cannot resolve the query. If Disable recursion (also disables forwarders) is set, the server will attempt to resolve a query from its own database only. It will not query any additional servers. If neither of these options is set, the server will attempt to resolve queries normally:... the local database is queried... if an entry is not found, the request is passed to any forwarders that are set... if no forwarders are set, the server will query servers on the Root Hints tab to resolve queries beginning at the root domains.Hope this is helpful rk

How DNS server caching works?
If a client send a query requesting for a particular web page to the DNS server and if the DNS server resolves the page from the other DNS servers & it will be store the same page in the DNS cache and it will give the response to the client with the requested page. If again the same web page is requested by any client then DNS server will get the web page from the DNS cache instead of again fetching the same page from the internet. With this there wont be any delay for the client to get the web page. This helps in bandwidth control. This is how the DNS server caching works.

When would a dns server contact a root server?
If a DNS server cannot find the answer to the DNS Query in its own database it will first query the forwarders (if there are any configured) and then ask the root server. root servers (by default) are the master DNS servers of the Internet.
