snetcfg在XP下为何首次不能自动安装驱动

用XP DDK自带的netcfg例子编译完毕后，用下面命令实现自动安装，在2000下是可以的，但在XP下首次安装时虽然网络属性里驱动passthru已经安装上去了，但实际并没有完全安装完毕，而且过程也没有数字签名验证对话框出现。但是，删除之后用手动安装的方式，就会有数字签名验证对话框出现，安装也是完全的。之后就可以正常实现自动安装了。
snetcfg -l D:\\build\\2kpassthru\\inf\\netsf.inf -c s -i ms_sfilter

请问各位在做XP自动安装时遇到这个问题么？
哪位大侠能告知一下这是什么原因？
谢谢先

我 现在在win2000上也遇到这个问题了
是不是因为打了补丁的问题呢？

应该是下面这个原因了
-------------------------------------------

Recently we ran into this issue with one of our customers. Sorry for not
communicating to the group immediately.

The problem is that the snetcfg uses SetupCopyOEMInf to copy the NetService
INF into the INF directory and it doesn\'t copy the miniport INF. Because we
thought the system would do so by following the CopyINF directive. This is
not true.

The \"CopyINF\" directive, by design, is only observed if the original INF is
not yet in the INF directory. So to work around the problem, you have to
update your installation app (snetcfg) to also copy the Net class (miniport)
inf using SetupCopyOEMInf when it comes to installing IM drivers.  Make sure
you specify a fully qualified path of the INF in the SetupCopyOEMInf
arguments.

We will probably right a KB on this issue.

好像有更好的方法
snetcfg -l .\\netsf.inf -c s -i ms_passthrus
netcfg -l  .\\netsf_m.inf -c s -i ms_passthru

我在XP下用bindview安装passthru也有这个问题，哪位高手解答一下疑惑啊~
