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).

11 Habits You Need to Stop Doing

Stop watching too much TV If you spend too much time watching TV, you are wasting your life away. I feel really strongly about this one. I don’t have cable, and while I do watch some shows on Netflix, it’s few and far between. I only watch TV after I really am relaxed and need a break. I’m also careful not to turn on the TV right when I get home. I find that if I do this, I’m sucked in. This is why I keep my reading list and focus on reading good books instead. So, start to pay attention to how much TV you’re watching. If you think it’s too much, cut back. Limit your TV intake to 30 minutes to 1 hour per day, if possible. Stop talking about people behind their backs Talking about someone behind her back is a bad idea for a number of reasons. First, if someone is talking to you behind someone else’s back, you can bet on it that they also will talk about you. Second, did you know that when you talk about someone negatively, the person who you’re talking to will associate yo...

How to Stop Porn Addiction

Don't be judgmental. The first thing you should do when trying to help other people stay away from porn is to stop being judgmental. Do not see or portray the situation in a way that makes them bad for what they do. Sexuality is very normal and human. Even most religions teach that it is not anyone’s place to judge their fellow man (but is instead the job of the Creator). It’s also bad to judge people because it tends to turn them off from what you’re trying to do. Many people that might be open to change will become defensive if you judge them and become even more set in their ways. Stay calm when you talk to them and avoid any judgmental language like “Why can’t you be more like Davis ?” or “Watching pornography will turn you into a pedophile!”. Don’t make assumptions about how they think or compare them to other people, since language like this tends to shut people down. Look for spiritual guidance. If you’re really having trouble getting your habit under control, you ...

Boss Discovered My Side Job And Threatened To Fire Me!!

Here is Judy’s Story I have been working for my current boss for close to 3 years now. The job is okay, it’s just that my salary has not been increased during this whole time. I have been struggling to make ends meet and to be honest, I have been surviving on loans from here and there. A few months back, a friend of mine introduced me to a guy who offered me an online job and a salary that is equal to the one that my boss pays me. The job was so flexible, so I quickly agreed to do it. To juggle the two jobs, I have been getting to work very early and then I start with the workload for my ‘actual’ job and then when I am done, I tackle the other job which is so much more flexible and easier. I have really been enjoying this because every end of the month, I get not one, but two pay checks. I have found financial freedom that I never thought was possible. I can even afford to save cash for the future However, I am afraid I messed up and it may cost me my job. I got to work very...
