A STOP error message in Windows Server 2000 can occur due to various logical and physical factors. Unmountable hard drive and data inaccessibility are the two major causes of concern for any computer user after the STOP error message appears. An ideal solution to overcome STOP error message is by restoring the data from an updated backup. However, if you have not maintained any backup or backup fails to restore the desired information, then you will need to opt for advanced Partition Recovery software.

  As a practical instance, you run a program that runs NetBIOS functions. A NetBIOS function is primarily executes and interprets a specified network control block. The program runs for a long time and your system freezes or stops responding while the program still continues to run. After some more time, you encounter the below error message:

  “STOP 0x00000041 MUST_SUCCEED_POOL_EMPTY (0x1000, 0x440, 0x2E, 0x1)” The four parameters in the above STOP error message vary due to system’s configuration.

   Parameter 1: The size of the request that could not be satisfied (0x1000)  Parameter 2: The number of pages used of NonPaged pool (0x440) Parameter 3: The number of > PAGE_SIZE requests from nonpaged pool (0x2E) Parameter 4: The number of pages available (0x1)

  After the above error message appears, all the hard drive data becomes inaccessible. Additionally, you encounter the same error message every time you attempt to boot your computer system.  

Cause:

  The above STOP error message primarily occurs because of a pool memory leak in the Netbios.sys driver.

  Resolution:

  To troubleshoot and resolve the above error message and access the data, you will need to follow the below measures: Install the latest service pack 4 (SP4) for Windows 2000. Apply the Hotfix solution provided by Microsoft.

Restart the computer system.

  If you encounter the same error message even after applying the Hotfix solution, then you will need to perform a clean reinstall of Windows. A fresh reinstall of Windows will completely erase the data stored in the hard drive partition. To recover the data in such situations, you will need to use advanced partition recovery software. These File Recovery applications are built with interactive user interface that makes them easy to understand and implement.    Stellar Phoenix Windows Data Recovery is a powerful and reliable file recovery application.
