First Step involved in troubleshooting Event ID 2020 Windows 2003

1. Start Registry Editor (Regedt32.exe).
2. Locate and then click the following key in the registry:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Memory Management
On the Edit menu, click Add Value, and then add the following registry value:
Value name: PoolUsageMaximum
Data type: REG_DWORD
Radix: Decimal
Value data: 60
Setting the value at 60 informs the Memory Manager to start the trimming process at 60 percent of PagedPoolMax rather than the default setting of 80 percent.
If a threshold of 60 percent is not enough to handle spikes in activity, reduce this setting to 50 percent or 40 percent.

Value name: PagedPoolSize
Data type: REG_DWORD
Radix: Hex
Value data: 0xFFFFFFFF
Setting PagedPoolSize to 0xFFFFFFFF allocates the maximum paged pool in lieu of other resources to the computer.

3. Quit Registry Editor.
4. Restart the server for the changes to take effect.
