Windows 2003 Event ID 2020

I am currently experiencing a problem with our domain controller. We are experiencing the following error and the server eventually locks our users out.

Event ID: 2020 Source: Srv
Source: Srv
Type: Error
The server was unable to allocate from the system paged pool because the pool was empty.

There is 4GB of RAM and memory usage is about 1.6GB. How do I resolve this issue? We have a Livevault internet backup and I've checked that no two backups are running at the same time. This issue happens every two weeks.

The problem seem to disappear after updating the drivers.

I applied the registry fix outlined in The systems still froze. I've just applied all the driver updates for the HP Server using the HP Software update tool. I have yet to restart.

To set the DynamicMemory registry parameter on computers that run Windows Server 2003 with Service Pack 1 (SP1) or later versions, follow these steps:
      1. Click Start, click Run, type regedit, and then click OK.
      2. Locate and then right-click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

      3. On the Edit menu, point to New, and then click DWORD Value.
      4. Type DynamicMemory for the name of the DWORD, and then press ENTER.
      5. Right-click DynamicMemory, and then click Modify.
      6. In the Value data box, type the value that you want to use, and then click OK.

The value of this parameter is in gigabytes (GB). For example, if you set the value to 1, the kernel reserves space for a total of 1 GB of system memory or for the total amount of physical memory that is installed at startup time, whichever is larger.
      7. Exit Registry Editor, and then restart the computer.

I am also receiving an error regarding the applications event log being corrupt. I disable the Event log service, rebooted, deleted the file and restarted the service. But the issue returned a couple of hours later. One suggestion was to change the NIC to full duplex. Would this work and can I do this remotely and regain access to the system?

Also would a chkdsk /f on the hard disk help fix the application log and memory pool depletion issue?
