Connection-specific DNS Suffix default setting 1

[Andytanu]

I'm a newbie to a world of computing.
I'm looking for a way to add/change 'Connection-specific DNS Suffix' back to default setting. How to do that?

I once hook-up my laptop to a company's domain network I used to work for.
Now every time I type ipconfig in CMD box, it always show that company's domain, such as: intra.excelco.co.id

I can't do it though with command: ipconfig /release.

Pls help. I know it's a piece of cake for you guys. Heap of thanks.

Well, the default is blank, so you just need to go into TCP/IP settings (Right-click network connection, go to properties, select TCP/IP, then click Properties), go to the DNS tab and remove the domain suffix.

There may also be settings in System Properties (right-click My Computer), Network ID (or Computer Name if XP), remove the computer from that domain if it's still a member, also check the "More" button and make sure there's no DNS suffix in there.

Hi chipk,

Heap of thanks!!! I've done it.

One more, what state should Disabled NETBIOS over TCP/IP be? Checked or Unchecked. I just heard from friend of mine that if this is enabled then it is potential for someone to sneak-in into your comp.

Again thanks for your info. Wish you all the best.

If you're not on a Windows network where you're sharing files, then you don't need NetBIOS. HOwever, you have to remember that you disabled it if you ever want to join a workgroup or domain, otherwise that won't work for you. If you're not doing any file sharing, you can also uncheck File/Print Sharing and Client for MS Networks in your Network Connection (basically everything can be unchecked except TCP/IP.

Your last comment triggered me to ask you for a final advice from you.
In Network Connection there is Microsoft TCP/IP Version 6, should I unchecked this too? Heard this is the latest IP tech (IPv6) people are talking about for quite sometimes.

As for File/Print Sharing concern, I always unchecked it.

Thanks chipk... Have a good day...

It's highly unlikely that you're using IPv6. It is the newer technology (than IPv4), but not as widely deployed. An IPv6 address is hexadecimal (instead of binary like IPv4) and is 128 bits long, which means you have some ridiculously high (in the trillion trillion) number of available addresses, whereas with IPv4, there are only 4.3 billion address available.

That being said, the short answer is no, you don't need IPv6 enabled, as long as IPv4 is on.

Wikipedia has a good article, with lots of external links:

http://en.wikipedia.org/wiki/IPv6.

Although some techs are anti-wiki, it's a good place to start, and much easier than reading RFCs, which this article has links to at the bottom.
