Description
Problem description
When enabling Accelerated networking the NetBios resource will detect a NetAdapter Mellanox which is not IP Enabled. In module 9.0.0, it will write to registry if IPEnabled = false, but the resource fails with the following error record:
"ErrorRecord": "Cannot find path \u0027HKLM:\SYSTEM\CurrentControlSet\Services\NetBT\Parameters\Interfaces\Tcpip_{3457DBDB-ED8E-448C-8BAE-525091A1FD48}\u0027 because it does not exist."

DSC configuration
NetBios DisableNetBios
{
InterfaceAlias = '*'
Setting = 'Disable'
}
Suggested solution
No, but I am hoping the gurus here have.

Research direction
Start by reproducing the NetBios DisableNetBios configuration with InterfaceAlias='*' on the stated Windows Server 2019 Azure VM, then inspect how the resource handles the non-IP-enabled Mellanox adapter and the missing NetBT registry path. Done means the configuration completes without the reported path error while Accelerated Networking remains enabled.
