Resolve

Check system account privilege level

To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

Open the Registry Editor and check 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
  1. Check that the System account has read/write permission for each registry key. To check the permissions:
    • Right-click each registry key, and then click Permissions.
    • Check whether the System account has read/write permissions for the key. If it does not, add them.
  2. Check that the paths to all dynamic-link libraries (DLLs) are correct. If a path to a DLL contains any environmental variables (such as %systemroot%), check that the variables are valid for the operating system. Environmental variables might need to be expanded.
