>My Laptop is having a computer name Laptop. From my PC, I usually Terminal Server to it by simply selected Laptop in the list of remote desktop connection dropdown list of connections I have done so far.

>This is my internal network. It has nothing to do with the Internet. Now, from my PC, when I ping Laptop, it pings to Laptop.levelextreme.com, where the IP is my main server. I really cannot see any relation with that. After a while, it pings locally. But, then, it started to ping to Laptop.levelextreme.com and this is what it is now.

Couple of thoughts - is the laptop part of the domain, and is it connected to your domain when you're doing this? Kinda sounds like sometimes it's part of the domain and others it's not???? Of course that doesn't explain whey the ping returns your servers address ...
