Window 11 24H2 / Can't Join Domain

Anonymous

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 08:09:17:784 -----------------------------------------------------------------

08/28/2024 08:09:17:784 NetpValidateName: checking to see if 'XPS' is valid as type 1 name

08/28/2024 08:09:28:877 NetpCheckDomainNameIsValid for domainname returned 0x54b, last error is 0x0

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.

tried that also before a few times but no fix. something else is causing this. so far no solutions to be found anywhere. i tried registry options and anything else i could find.... re-installing does not seem to fix it also. I can log into the domain but then i am forced into the guest network connection that wil limit functionality like network drives. only PVN connection over Citrix works and then i am logged into the .local network. only problem here is that it is extremly slow....

Good Day, we had a similar issue with our domain joined devices. Specifically when upgrading to Win11 24H2.

What we found was a Encryption policy during GPO assignment was not deploying to devices.

The policy in question is located under the following location:

Local Computer Policy - Computer Configuration - Windows Settings - Security Settings - Local Policies - Security Options.

Policy is called Network Security: Configure Encryption types allowed for Kerberos. And we then enabled the following options to be applied from GPO:

RC4_HMAC_MD5

AES128_HMAC_SHA1

AES256_HMAC_SHA1

Future encryption types

Also a good idea to check the following on the client side that is not joining and updating the reg key provided for it to receive the policy.

Also a good idea to test this policy first before deploying to all devices.

On the client side
1. If a policy is specifying a kerberos encryption key then you will need to change the following in the registry
2. The key will not be present if a policy is not applied
3. Faulty entry in registry
Registry Hive: HKEY_LOCAL_MACHINE
Registry Path: \Sofware\Microsoft\Windows\CurrentVersion\Policies\System\Kerberos\Parameters\

Value Name: SupportedEncryptionTypes

Type: REG_DWORD
Value: 1, 2, or 3 are a finding.
1. Registry Hive: HKEY_LOCAL_MACHINE
  Registry Path: \Sofware\Microsoft\Windows\CurrentVersion\Policies\System\Kerberos\Parameters\
change to Value Name: SupportedEncryptionTypes 7ffffffc 2. Pc will need to restarted 3. Run a gpupdate /force to enforce the new policies

Our functional Domain Level is Server 2016

Hope this info is of assistance
Regards
