楼上的方法应该不行吧？你这样写，只枚举出display type 为network的结点。如果要枚举出所有的计算机，应该先枚举所有的network.然后枚举network下的domain，然后再枚举domain下的server才对，server才是局域网上的计算机。Bloblo，我自己写了一个类去实现类似的功能，不过由于完全按照面向对象的要求去写，而且在枚举网络资源时用到了多线程，代码比较长，如果你想看明白也要一段时间，你要不要？我写的这个东西有两个特点：
1）多线程枚举，当网络情况复杂，计算机多的时候不会影响用户的其它操作。
2）由于是封装成一个类，使用简单。如果你不想要，下面有两个例子，对你应该有用，是转贴自别人的代码。procedure GetDomainList(TV:TTreeView);

dwDisplayType :=RESOURCEDISPLAYTYPE_DOMAIN;
dwUsage :=RESOURCEUSAGE_CONTAINER;
lpLocalName :=NIL;
lpRemoteName :=NIL;
lpComment :=NIL;
lpProvider :=NIL;
end;
{ get net root }
ErrCode:=WNetOpenEnum(
RESOURCE_GLOBALNET,
RESOURCETYPE_ANY,
RESOURCEUSAGE_CONTAINER,
@NetRes[0], EnumHandle
);
If ErrCode=NO_ERROR then begin
EnumEntries:=1;
BufferSize:=SizeOf(NetRes);
ErrCode:=WNetEnumResource(
EnumHandle,
EnumEntries,
@NetRes[0],
BufferSize
);
WNetCloseEnum(EnumHandle);
ErrCode:=WNetOpenEnum(

EnumHandle
);
EnumEntries:=1024;
BufferSize:=SizeOf(NetRes);
ErrCode:=WNetEnumResource(
EnumHandle,
EnumEntries,
@NetRes[0],

);
IF ErrCode=No_Error then with TV do try
a:=0;

While a How can I get the contents of the Neighborhood? The following unit defines a component, TNetworkBrowser, which can be used
to enumerate all resources on the network in a hierarchical tree. The
actual browsing takes a long time (try opening "Entire Network" in Windows
Explorer). If you set the Scope property to nsContext, you'll see the list of machines from the "Network Neighborhood" window.
下面的一个单元定义了一个组件. TNetworkBrowser, 可以枚举hierachical树上所有
的网络资源. 实际上浏览是要花费很长时间的,这您可以通过在WINDOWS资源管理器
中打开"整个网络" 来比较一下. 如果你设置SCOPE属性为nsContext , 你就可以看到
和网络邻居中一样的机器列表 Yorai Aminov
