网络访问时you might not have permission to use this network resource错误解决方法

今天公司停电，本想一起去和同事们搓麻消磨一下，不巧的是，他们人手刚好，其实这样也好，我可以一心回家来做点事情，
家里的两台电脑共享时总是有点问题，现在终于有时间可以来处理一下了。

现状是：
两台电脑透过HUB共同连线ADSL上Internet，其中一台是Vista，一台是XP-SP2，当我在Vista上访问XP电脑上共享的资源
时，总是提示我 you might not have permission to use this network resource...在网上搜索了一下之后，按照别人的方案
试了以下步骤，最终OK。

1）修改注册表

1. Click Start, click Run, type regedit in the Open box, and then click OK.
2. Locate and then double-click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
3. In the right pane, double-click restrictanonymous.
4. Make sure that the value in the Value data box is set to 0, and then click OK.
5. Close Registry Editor.
6. Restart the computer.

或者
I located the subkey in Regedit, and I found the value of 'restrictanonymous' was 0, then I modified the value of another subkey im same location named 'limitblankpassworduse' and set it to 1, then I could access to this computer.

You can try this and have a good luck!

2）在XP的电脑上增加Vista系统使用的帐号
3）修改Vista电脑群组。
