Windows Server 2022:

EventId 14550, DfsSvc – “The DFS Namespace service could not initialize cross forest trust information on this domain controller, but it will periodically retry the operation. …”

While setting up a DC for a new forest in Windows Server 2022. a strange issue has observed. ADDS has been setup and promoted the server as the Domain Controller for the new forest/domain. But none of the AD tools were not able to open, says a DNS error always

When digging into the machine, error messages found on the Event viewer are:

The DFS Replication service failed to contact domain controller to access configuration information. Replication is stopped. The service will try again during the next configuration polling cycle, which will occur in 60 minutes. This event can be caused by TCP/IP connectivity, firewall, Active Directory Domain Services, or DNS issues.

Additional Information:

The errors indicated that there is a problem with DFS and sysvol seems to be not accessible.

Here is the solution to fix the issue

Go to Registry editor and open the key SysvolReady at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters

If the value of the key is 0 change it to 1. If the value is 1 change it to 0 and ‘Accept’, again change to 1 and accept. Exit registry editor.

Great!!! Worked like a charm.
