Qt uses deprecated Windows Layered Service Providers api resulting in wall of errors on Windows 11

We get this in our app and others have the same issue (although this issue is probably wrongly reported for being an QtCreator error) https://bugreports.qt.io/browse/QTCREATORBUG-26365 and the closed Fortune Cookie example: https://bugreports.qt.io/browse/QTBUG-100669

GetHostByName is listed as deprecated, but GetHostName is not and also displays the same behaviour. In both cases the method queries any available namespace service providers first and then falls back to querying the NetBIOS name if none are found. As of Win11 it seems the call to enumerate the namespace service providers fails internally, generating the debug output you see.
