获取域用户

Question

  如何获取其他域中用户名字。通过编程实现。急急！！！

Answer 1

你说的应该是工作名吧.
你用下面的GetGroup()能获得局域网中的工作组名,不知是不是你要的域名.OnSelchangedTreeNetcomputer(..)是一个树控件的SELCHANGE事件,
你参考

Answer 2

我说的是这样的：      假如我在域A中，在网络中有一个不B域， 并且A,B同属一个forest域， 现在我想得到B域中的所以用户名，以及Group。     应该怎样办？怎样用程序实现？A,B域是 信任域 和 非信任域两种情况时 ，处理的情况一样吗？
谢谢！！
