服务器无法通过系统非页面共享区来进行分配，因为服务器已达非页面共享分配的配置极限。

看样子必须用IE才能访问“http://social.technet.microsoft.com/Forums/zh-CN/window7betacn/thread/88ed518a-9381-47e8-9a96-8cbd2986ccb8”。

设置了下，目前没出现不能访问的了：

1. Click Start, type regedit in the Start Search box, and then click regedit in Open box. Press Enter.

If you are prompted for an administrator password or confirmation, type your password or click Continue. 

2. Please expand to Computer, click "File" menu and click "Export".

3. Please name the file as "RegBackup" (without quotation marks) and then save it to the C:\ drive as a backup.

Note: In case we need to undo the modification, we can double click this RegBackup.reg file to restore the registry key.

4. Locate and then click the following registry subkey:

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

5. Highlight the LargeSystemCache key and set the value to 1.

6. Please also locate the following key:

HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size

7. Modify the value of the Size key to 3.

Then, restart the machine and check whether the issue persists.
