Things look good today

Setting up a small home network had always been a "dream" for me. How I wish it comes true since the time I first wished for it, and today this tiny dream of mine had been realised.

Well, actually I'm not very IT- proficient. Since I'd been working for the last two months in my company now, things had changed. I get to expose myself more to the IT side of the working world, though I am not an IT engineer. Well, takes a while to explain my job scope but I'm not going to do it here.

It's about a good nice day today that I had spent half of my day on setting up the network and troubleshoot a problem which my "pro-IT friend" cannot solve for me.
Geez, so any of you wanted to give that a try?
Two computers which couldn't ping each other, and yet internet connection is established between the two. What went wrong? File and printer sharing are not available. And all settings and IPs are set as proper as you may defined.

Well, the problem was solved. I will leave the answer open for all. Now why do I wish for something that 'simple' so much. For it's the main cause of problems--my dear sister, she'd always been "taking over" my pc when I needed to do my work or listen to my music most. Kind of irritating, you got me?

Okay, since the roots of this problem had been removed, I supposed there will be peace in my room once again, and I will live happily ever after again.

joo.
