Every Windows Network Admin Must Know..

1. DNS Lookup

The domain naming system (DNS) is a cornerstone of every network infrastructure. DNS maps IP addresses to names and names to IP addresses (forward and reverse respectively). Thus, when you go to a web-page like www.windowsnetworking.com, without DNS, that name would not be resolved to an IP address and you would not see the web page. Thus, if DNS is not working "nothing is working" for the end users.

DNS server IP addresses are either manually configured or received via DHCP. If you do an IPCONFIG /ALL in windows, you will see your PC's DNS server IP addresses.

So, you should know what DNS is, how important it is, and how DNS servers must be configured and/or DNS servers must be working for "almost anything" to work.

When you perform a ping, you can easily see that the domain name is resolved to an IP (shown in Figure 2).

They are happy to go to Club Cubano but will never forget you if you upgrade them to Mojos. They wear their plastic weaves long and coarse, the ones you comb until the scalp protests. The polish on their nails — mostly blue — is chipped and their lipstick ghetto; the ones bought at Moi Avenue for Sh200. Their dreadlocks — if they happen to have them...

There is no regret in Obedience

It’s a guarantee your life will never be the same again when you obey God. God is our CREATOR and our DIRECTOR meaning he knows the best way for our lives since he loves us, our role is to simply OBEY Him. Obedience is everything when we are relating to God. Obedience is the KEY ingredient in the kingdom of God. God is always ready to manifest himself in our lives when we obey Him and his word(John 14:23 Jesus Replied, “Anyone who loves me will obey my teaching. My Father will love them, and we will come to them and make our home with them.” Like 5:5 Simon Peter an experienced fisherman with a fishing business had toiled the whole night without any catch of fish and he was frustrated and tired and he was washing his nets UNTIL Jesus told him to Launch out into the deep again. Peter had a CHOICE to say YES or NO but he choose to OBEY and he said: “Nevertheless AT THY WORD I WILL LET DOWN THE NET”. The moment he chooses to obey instead of Questioning, Analyzing and trying ...
