nsrnmsqlra -i 

这无法注册并显示错误：  Cannot open client side named pipe for authentication：Cause is related to Windows （SMB） Server Message Block protocol.（无法打开客户端名为 pipe 进行身份验证的管道：

因为与 Windows （SMB） 服务器消息块协议相关。

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.
