To fix the following error in the event log:
The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations.
Event ID: 2017
Most likely the computer just needs a reboot after you’ve done some Windows Updates. However, if that doesn’t fix it, make the following two registry changes:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache = 1
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size = 3
Then reboot the computer.
More information: The error causing event 2017 is caused by a high volume of traffic on the computer. Windows 7 has a configured limit for nonpaged pool allocations and is not designed for this amount of traffic. Making the above registry changes increases the limit for nonpaged pool allocations and should clear the error.
