I HAVE BEEN PULLING MY HAIR OUT FOR THE LAST TWO DAYS.
With the knowledge from this thread of comments:
Yes the win 11 24H2 updates does not let you join a single label domain.
I adopted a single label domain when joining the company and adding devices to the domain has NEVER been a huge issue until two days ago when imaging a brand new laptop from dell for office staff.
The thing that let me to success was seeing the registry edit suggestions. I didn't think that was necessary at first so i kept troubleshooting and troubleshooting, going crazy in the end so then finally I added a registry key and i finally got the prompt for credentials.
I almost threw the laptop across the room. Special thanks to AI/GPT and the users in this thread. Anyway here is the special sauce:
To join a Windows 11 computer to a single-label domain, you need to access the system settings, navigate to "Computer name, domain, and workgroup settings", select "Domain" as the membership type, and enter the full single-label domain name, but be aware that this configuration is not recommended due to potential compatibility issues and may require additional registry adjustments to enable single-label domain resolution on the computer; you might need to create a DWORD value called "AllowSingleLabelDnsDomain" in the registry with a value of "1" to allow joining a single-label domain.
Key points to remember:
- Not recommended:
Single-label domains (SLDs) are generally not recommended due to potential issues with DNS resolution and compatibility with certain applications.
- Registry modification:
To join an SLD, you might need to manually edit the registry on the computer to enable single-label DNS resolution by creating the "AllowSingleLabelDnsDomain" DWORD value.
How to join a single-label domain:1. Open System Settings: Go to Start menu, then select "Settings" > "System" > "About". 2. Access Computer Name: Click on "Change" under "Computer name, domain, and workgroup settings". 3. Select Domain: Choose "Domain" as the membership type. 4. Enter Domain Name: Enter the full single-label domain name (e.g., "example"). 5. Registry Modification (if necessary):
- **Open the Registry Editor.**
- **Navigate to HKEY\_LOCAL\_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters.**
- **Create a new DWORD value called "AllowSingleLabelDnsDomain" and set its value to "1".**
