How to configure equivalent of Linux /etc/resolv.conf search domain.com in MS Windows – DNS Suffix

Linux's default file that defines what DNS servers will be used /etc/resolv.conf typically contains directives with the default search domain or domains; used for FQDN (Fully Qualified Domain Name) completion when no domain suffix is supplied as part of the  DNS query. Lets say sub-domains under domain.com  has to be accessed (in /etc/resolv.conf) there is:

search domain.com

That is very handy whether you have to ssh or open in web browser (sites) or multiple servers each residing under a single main domain name (for example:
server1.domain.com, server2.domain.com, server3.domain.com etc.) by typing in browser or SSH by only passing the sub-domain name i.e.:
 

http://server1
http://server2

or

ssh user@server1
ssh user@server2


Here is /etc/resolv.conf from pc-freak.net

# cat /etc/resolv.conf

domain pc-freak.net
search pc-freak.net bergon.net

 

Here is example of what I mean, ascii-games is a sub-domain of pc-freak.net (ascii-games.pc-freak.net) and is resolved with no need to type full FQDN

 

# host ascii-games
ascii-games.pc-freak.net has address 83.228.93.76


The DNS server knows that all failed to resolve queries by set DNS should be searched (resolved) under the defined search domain, i.e. each DNS query for server2, serverX (would try to be resolved as a subdomain of domain.com).

Therefore, a very good question is what is Microsoft Windows (2000, 2003, 8) OS equivalent way to define search domain.com into /etc/resolv.conf?

In Windows the same /etc/resolv.conf hosts search is done using the so called "DNS Suffixes".

DNS Suffixes are used for resolv of (domain name strings with no dots).

Adding a new DNS Suffix in Windows is done from

Control Panel -> Network and Sharing Center -> Change Adapter Settings

 

Here select LAN card Adapter used to bring Internet to Win host,be it Local Area Connection or

Wireless Network Connection

 and choose:

dialog select

and again click on

On next dialog click on

 

Advanced (button) -> DNS (tab)

In field
 

DNS Suffix for this connection

fill in host which you would like to resolve with no need for FQDN and press the

Add


(exactly like adding search pc-freak.net in  /etc/resolv.conf on Linux host). Add multiple hosts DNS Suffix, if you want to access subdomains naming from multiple base domain.
