Windows 7 Find solution for xp lost network share from windows 7 afters couple of hours

[Ronin]

PROBLEM :

Network shares created on Windows 7 and being accessed by Windows XP workstation are lost after a certain amout of time. XP never be able to access Share made on 7 until 7 is rebooted. You can still ping 7 from XP.

WHAT I FOUND :

Default configuration of Windows 7 (and Vista) for Network sharing is not well balanced. This must be fixed in registry. I found in event viewer (Administrative Event) a lot of SRV error #2017. This error is directly related with lost network sharing (Xp --> 7).

HOW TO FIX IT :

Start RegEdit, go here an set the following registry key to "1" :
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

Set the following registry key to "3" :
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size

Reboot Windows 7. You will never have Network share drop again.
I think this fix can also be applied for Vista.
