windows 7 打开sharepoint 2007上的office文档需要输入用户名和密码

在windows 7 的机器上直接打开sharepoint网站正常，但是打开sharepoint 2007上的office文档需要输入用户名和密码。

已加入域。域中xp系统正常。

问题主要是windows 7和vista系统本身导致的

按微软kb的方法修改注册表：

After you apply this hotfix, you have to create a registry entry. To do this, follow these steps:

Click Start, type regedit in the
Start Search box, and then press
ENTER.
Locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters

On the Edit menu, point to
New, and then click Multi-String Value.
Type AuthForwardServerList, and then press
ENTER.
On the Edit menu, click
Modify.
In the Value data box, type the URL of the server that hosts the Web share, and then click
OK.

Note You can also type a list of URLs in the
Value data box. For more information, see the "Sample URL list" section in this article.
Exit Registry Editor.
