NetWorker NMM SQL Server Remote Agent kann nicht registriert werden - nsrnmsqlra -i

NetWorker NMM SQL Server Remote Agent kann nicht registriert werden. Wenn NMM auf einem SQL Server installiert ist, muss es (automatisch) einen Remote-Agent bei NetWorker registrieren.
Verwenden dieses Befehls

nsrnmsqlra -i 

 

Dies kann nicht mit dem folgenden Fehler registriert werden:  Client side named pipe for authentication:

Cause steht im Zusammenhang mit dem Windows (SMB)-Server Message Block-Protokoll.

Das Microsoft Windows-Betriebssystem verwendet NamedPipes für die Authentifizierung und den Zugriff auf Dateien, Drucker und Freigaben.

NamedPipes verwenden Server Message Block (SMB) als zugrunde liegendes Transportprotokoll.   

Wenn SMB deaktiviert ist, schlägt der NMM-Remote-Agent aufgrund der Authentifizierung fehl, die die Verwendung von NamedPipes erfordert.

Technische Ursache definiert als:

Named Pipe uses the SMB protocol. Please find reference link.

[[MS-WPO]: Named Pipes | Microsoft Learn|https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-wpo/4de75e21-36fd-440a-859b-75accc74487c]

This is windows requirement.
 
During authentication process, Server will create the named pipe file in the client and open the named pipe to get the RPCSEC_GSS 
credentials. But when SMB protocol is disabled,  server fails to get the details from the client.

HINWEISE

1. Auf Microsoft Windows-Servern ist die SMB1-Funktion standardmäßig installiert. 

2. Ab Windows 2019 Server ist SMB1 standardmäßig nicht installiert.
Wenn SMB also ebenfalls deaktiviert ist und SMB1 nicht installiert ist, schlägt der Remote-Agent fehl.
