| Description | Unexpected error - There are no protocol sequences available. NT ID 0xc00206b7 |
| Event Information | According to Microsoft: CAUSE: The HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\ClientProtocols registry key is absent. It is likely that the removal of a previous software application removed this key by mistake. RESOLUTION: Replace the key in the registry and it enables the system attendant to start. Import this registry key from a Microsoft Windows 2000-based server that has the same protocols installed on it. You can manually rebuild the ClientProtocols folder and add all the protocol values, but it is recommended that you import this key from a Windows 2000-based server running with the same protocols. |
