cifs mount error(12): Cannot allocate memory

I had some issues when I started to use autofs to mount windows shared from linux. The shares would go missing from linux and result in this kind of error:

mount error(12): Cannot allocate memory
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)

To fix this, I used the advice from here:

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

Then just restart.
