We have about 500 PCs on our domain. Functional level is Server 2016. We received our first laptop from Dell which shipped with Windows 11 Pro 24H2 and it will not join. Since it's failure, I've tested various versions of Win10 and Win11 not running 24H2 and they all join just fine.
netsetup.log shows:

08/28/2024 08:09:28:877 NetpCheckDomainNameIsValid [ Exists ] for 'domainname' returned 0x54b
The PC attempting to join sits on the same subnet as our DCs and there are no security appliances/firewalls filtering traffic.
From the 24H2 PC that won't join, I have tried or am able to:
- perform name resolution to various hostnames via nslookup
- verified inbound/outbound AD ports are open on our DCs
- DCs are replicating and are healthy (other PCs join w/o issue)
- Access any other resource on our LAN
- Tried statically assigning DNS servers (which are our DCs) on the PCs NIC
- Disabled Windows firewall on the PC
- Factory reset the laptop (Dell XPS 13 9345) and attempted again with no success
Another post suggest searching for a registry key relating to NT4Emulator on the DCs in the event the domain ever had an NT4 DC. This key doesn't exist on our DCs and if we had a DC running NT4 here, it was way before my arrival.
I can't think of any reason why this laptop is different other than it's the first running 24H2. I can't seem to find anyone having this issue.
Any help or suggestions is appreciated.

2024-12-01T14:24:53+00:00 Thanks much Sebastien. After two days worth of trying various fixes listed on this and other forums, this very simple regedit allowed a fresh out of the box Dell workstation (Win 11 ver 24H2) to join our company domain.
