Hello,
I have an Active Directory Domain called company.local, however, the NetBIOS name is company.uk. The domain consists of x2 Windows Server 2008 R2 domain controllers and x2 Windows Server 2008 R2 NPS servers which service connections for our radius clients for 802.1x.
I want to upgrade the entire environment to Windows Server 2019, however, the issue I am experiencing is that when I introduce a Windows Server 2019 NPS server and point the RADIUS clients to it no one can authenticate and within the event viewer of the NPS server is it saying that it cannot find the domain company.uk, which is the NetBIOS name.
I doubt there is an easy way to rename the NetBIOS name in the environment, so I was wondering if there is a work around or does it mean we need to create an entirely new domain without a period in the NetBIOS name?
