我开发的向导一个机器，是被用来作为其他机器的备份。当它取代现有的机器，它需要设置IP地址，DNS，WINS，以及相匹配的主机名的机器被取代。

I am developing a wizard for a machine that is to be used as a backup of other machines. When it replaces an existing machine, it needs to set its IP address, DNS, WINS, and host name to match the machine being replaced.

是否有.NET（C＃），一库，让我这样做编程？

Is there a library in .net (C#) which allows me to do this programatically?

有多个NIC，每个需要单独设置。

There are multiple NICs, each which need to be set individually.

感谢您TimothyP为你的榜样。这让我感动在正确的轨道和快速回复是真棒。

Thank you TimothyP for your example. It got me moving on the right track and the quick reply was awesome.

感谢balexandre.您的code是完美的。我是在匆忙和已经适应的例子TimothyP联系，但我会喜欢有你的code越快。

Thanks balexandre. Your code is perfect. I was in a rush and had already adapted the example TimothyP linked to, but I would have loved to have had your code sooner.

我也开发使用类似的技术来改变计算机名称的程序。我会后在将来使订阅此问题的 RSS订阅的，如果你想成为更新通知。我可能有点清理后的今天晚些时候或周一得到它。

I've also developed a routine using similar techniques for changing the computer name. I'll post it in the future so subscribe to this questions RSS feed if you want to be informed of the update. I may get it up later today or on Monday after a bit of cleanup.
