Repair the DFS namespace error Windows 2008 r2
After you install Active Directory on Windows Server 2008 R2, you may start seeing the following error message after the server boots :
The DFS Namespace service could not initialize cross forest trust information on this domain controller, but it will periodically retry the operation. The return code is in the record data.
This occurs because the DFS Namespace service attempts to access Active Directory before it has completely initialized.
To resolve this issue, we simply have to force the DFS Namespace service to start after the Active Directory service has initialized. We can do this by setting the DFS Namespace service to depend on the Active Directory service as well as setting it to a Delayed Startup mode.
To make those changes, start regedit and make the following changes :
1.Navigate to the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Dfs
2.Modify the DependOnService value and add NTDS to the list.
3.Create a new DWORD value named DelayedAutostart and set its value to 1.
