Vista Event IDs 2021 and 2017

Postby guest » Fri May 09, 2008 9:54 pm

Situation: Windows Vista Ultimate edition with SP1 is unable to access the shared folder on a Windows Vista computer.

The error 2021 and 2017 are recorded in the event log on the Windows Vista computer

Cause: The error 2021 and 2017 in the Event log usually indicate the insufficient amount of space for server service to use nonpaged memory pool.


1. On the Windows Vista computer, click Start > type regedit.exe in the Start Search box, and press Enter.
2. Navigate to HKEY_LOCAL_ MACHINE\System\CurrentControlSet\Services\LanManServer\Parameters.
3. Changed the registry values MaxWorkItems =12000 and MaxNonPagedMemoryUsage 0x5000000.

Note: If the two values do not exist, we can manually create them. To create them, create a new DWORD and input the name: MaxWorkItems and set the value to 12000. Repeat this step to create
MaxNonPagedMemoryUsage and set the value to 0x5000000.
