I'm getting the following error message in the Event Viewer:

Initialization failed because the driver device could not be created. Use the string "000000000100320000000000D71000C013010000250200C004000000000000000000000000000000" to identify the interface for which initialization failed. It represents the MAC address of the failed interface or the Globally Unique Interface Identifier (GUID) if NetBT was unable to map from GUID to MAC address. If neither the MAC address nor the GUID were available, the string represents a cluster device name.

I searched through the registry for that string, and it couldn't find it. What can be done to fix it?

    Hi there,

    I'm Cherrelyn, I'm here to help and truly understand how concerning it is to see repeated Event 4311 NetBT errors in your logs. Please try to open Device Manager then click View > Show hidden devices. Expand Network adapters, and uninstall any greyed-out or ghosted entries. Open Registry Editor regedit and go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters\Interfaces

    Delete any entries that don’t match active adapters back up the registry first and reboot your PC.

    If the error still shows up, disabling NetBIOS may also help if you're not on a legacy network.

    Let me know how it goes and I'm here to guide you for further assistance.

    Warm regards,

    Cherrelyn

    How am I supposed to figure out which entries in the registry match active adapters in device manager?

    Hi guys.
    I had the same problem, which started after installing PROTON VPN. My AIO's screen started flickering black, especially when I was browsing Microsoft Edge tabs.

    This issue was related to RAM, but after running tests and it passed all of them, I discovered that the problem was related to virtual memory, which was set to be managed by Windows.

    So, I disabled the automatic management of virtual memory by windows and set it based on the calculation below:

    If you have 8GB of RAM, you multiply 1,024MB x 8GB = 8,192MB x 1.5 = 12,288MB, which will be the minimum paging file size, and 8,192MB x 3 = 24,576MB will be the maximum size. Since I have 16GB of RAM (two 8GB sticks), I multiplied the above results by two, getting:

    Initial Size: 24,576 MB

    Maximum Size: 49,152 MB.

    DONE!!

    Problem solved.

    I never got this error message again.
