Dear @msolijen,

Option #1:
If you want to remove NetBIOS component permanently on the device, you need to build a custom image with removing “SYSGEN_SMB_FILE and SYSGEN_SMB_UI” components, please use Vybrid winCE BSP and workspace to do that.

Option #2:
Please refer MSDN Windows Embedded Compact Platform forum for more information related NetBIOS discussion.

This https://social.msdn.microsoft.com/Forums/en-US/e14eae20-26ca-431d-b1cc-b166b7208b00/security-on-ethernet-for-win-ce-60?forum=winembplatdev would be more relevant to your topic.

Option #3:
Please try this quick approach, I didn’t test this. Please remove following registry using regedit (Start → Programs → ColibriTools–>RegEdit) tool and verify your issue is solved and let us know your feedback.

[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Netbios]
    "DLL"="netbios.dll"
    "Prefix"="NBT"
    "Keep"=dword:1
    "Order"=dword:11

[HKEY_LOCAL_MACHINE\Services\SMBServer]
    "DLL"="smbserver.dll"
    "Keep"=dword:1
    "Order"=dword:12
    "Prefix"="SMB"
    "Index"=dword:0
