nsrnmsqlra NSR critical Microsoft SQL server documentation provides details about the following SQL Server Provider error:
nsrnmsqlra NSR critical Shared Memory Provider: No process is on the other end of the pipe.

nsrsqlsv NSR critical Cannot login to SQL Server Default Instance.
nsrsqlsv: Shared Memory Provider: No process is on the other end of the pipe.

請參閱以下Microsoft連結。

https://learn.microsoft.com/en-us/sql/tools/configuration-manager/creating-a-valid-connection-string-using-shared-memory-protocol?view=sql-server-ver16
 

Connections to SQL Server from a client running on the same computer use the shared memory and named pipes protocols. 
Shared memory has no configurable properties. Shared memory is always tried first, and can't be moved from the top 
position of the Enabled Protocols list in the Client Protocols Properties list. The Shared Memory protocol can be 
disabled, which is useful when troubleshooting one of the other protocols.

結語

必須在 SQL Server 上啟用共用記憶體，以使 NMM 正常運行。
