The main problem I have been hearing this week is people using windows 7 as a file server or people trying to access their windows 7 machine in some way from a Windows XP machine. This is fine if the windows 7 pc gets regularly restarted, the reason for this, not fully known to me, is that windows 7 has an issue with memory allocation to system non-paged pool.
You may be getting this error log issued to your event logs:
Event ID: 2017
Description: The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations.
The fix is just a simple registry change below:
Set the following registry key to ‘1′:
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache
and set the following registry key to ‘3′:
This should definitely sort out the problem, if not please let me know.
I found a fix many months ago unfortunately I am unsure where I got it from, so I am not able to give recognition to the correct person.
