The Routing and Remote Access service could not start because it could not access required registry value(s). |
  |
The most common reasons for this error are:
- The registry key does not exist.
- The queried value does not exist in the registry.
- The SYSTEM account does not have read/write permissions for a registry key.
- The value of a required registry key is incorrect.
- The subkeys under the registry key could not be opened for one of the above reasons.

Open the Registry Editor, and verify the values of the following registry keys:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess\Parameters
HKEY_LOCAL_MACHINE\Microsoft\RAS\SecurityHost
HKEY_LOCAL_MACHINE\Microsoft\RAS\AdminDll
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess\Accounting
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess\Authenication
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess\RouterManagers
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess\DemandDialManager
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RemoteAccess\Interfaces
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RasMan\PPP
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\RasMan\PPP\ControlProtocols
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Rasman\PPP\EAP
Values to verify:
- Verify that the System account has read/write permission for each registry key. To check the permissions:
- Right-click each registry key, and click Permissions.
- Check whether the System account has read/write permissions for the key. If it does not, add them.
- Verify that the paths to all DLLs are correct. If a path to a DLL contains any
environmental variables (such as %systemroot%), verify that the variables are valid for the operating system. Environmental variables might need to be expanded.
