有一windows 7  共享文件夹无法访问, 后来发现如下的解决方案。

7's Windows Application/Security/System Logs.

"The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations."

i have resolved above issue making changes in registry.

Set the following registry key to ‘1':

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

and set the following registry key to ‘3':

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