Directory Service will be unable to respond to any RPC requests

[Ken Tech]

I got the following error in my Domain Controller, any one know how to
resolve it?

Event Type: Error
Event Source: NTDS General
Event Category: Internal Configuration
Event ID: 1656
Date: 3/9/2546
Time: 6:46:54
User: Everyone
Computer: SUN
Description:
The Directory Service was unable to find any RPC protocol sequences
installed on this computer, failing with error 1719. The Directory Service
will be unable to respond to any RPC requests as long as this condition
persists.

My DC server RPC service is running and dcom patch to protect from the
blaster worm has been applied.


Thanks,
Ken

This can occur if there are registry entries missing from
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Rpc\ClientProtocols. You can manually
repopulate the information or you can try removing and reinstalling "File
and Print Services".

The values in the registry should be:
"ncacn_np"="rpcrt4.dll"
"ncacn_ip_tcp"="rpcrt4.dll"
"ncadg_ip_udp"="rpcrt4.dll"
"ncacn_nb_tcp"="rpcrt4.dll"
"ncacn_http"="rpcrt4.dll"
