DNS Resolution is a means of directing persons to websites. DNS works similar to a phone book in assigning IP numbers to hosts. In doing so, we are able to connect to the internet through words rather than having to remember an IP address to visit websites.
DNS is used to resolve a fully qualified domain name (such as wiki.answers.com) into an IP address (such as 192.41.64.25).
One looking to resolve their DNS issues should enable reverse look-ups on their DNS server. Next, one should check for duplicate records on their DNS server. Finally, one should compare the records on their DNS server and make the necessary changes.

The type of structure DNS uses is hierarchical.
authoritative dns server is server that has own databases that has name resolution for the clients that for resolve from name to ip address and for ip address to name. non-authorititative dns server is server that forward request of dns client to authoritative dns server for resolve.
if the preferred dns server is blank then the system takes dns as the host server and try to resolve the entries from its own cache if it is able to do it then finew other wise it will show dns error on the IE page. same thing happens with the resources if its in the cache it will resolve the FQDN to IP othere wise will give error
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
You are getting the dns error because ther is no website or URL with the name ydhmrxd.com so dns cannot resolve it to any IP so its shows an error.
