Hi Douglas,

The main cause of the error is a poor memory leak with netbios.sys. The netbios.sys is a type of system file in Windows that is used in the execution and interpretation of specified network control blocks. The error will usually come up when you attempt to access a program that processes NetBIOS functions. When the program runs for a long time, the system may freeze or will simply just stop responding. 

Please follow below steps to resolve this error.

Step 1 – Download Microsoft HotFix
One of the best ways to solve the problem is to download the Microsoft Hotfix application. This is a program that has been specifically designed to address problems such as the stop 0x00000041 error. The hotfix needs to be downloaded and installed into the system for it to work. The Microsoft Hotfix can be downloaded directly from the Microsoft website.

• Go to this link
• Search for the Microsoft Hotfix and then download the provided file.
• Follow instructions on the website and make sure to complete them accordingly.

Improper installation of the product can only lead to more problems occuring. It’s also important to note that before hotfix can be installed into the computer system, there should be a Windows 2000 Service Pack 4 (SP4) installed in the computer. Without this, it will be impossible to properly install the program. The computer should also be restarted when the program is downloaded.

Step 2 – Update Windows

Another way to solve the problem is to update Windows. This will make sure that the system will be able to cope up with the demands of NetBIOS file and the programs that use it. To update your Windows version, go to Start>All Programs>Windows Update. Download all the necessary upgrades and install them properly.

Step 3 – Restart Windows

Often, once you have updated Windows, if you then restart the computer you will find that the Stop 0x00000041 error will have disappeared.

Step 4 - Use Registry Reviver

Registry Reviver is essentially a utility program designed to scan your computer for registry errors and fix them, to better optimize your computer’s performance and stability. It is the perfect tool to perform maintenance and optimize the Windows Registry. On periodic runs, you will be making sure your computer stays healthy and the Operating System error-free.
