In this post, I am sharing a script for checking the Network and Connect related permission of SQL Server User.

When you installed the SQL Server, for network access you should enable the TCP/IP pipeline and other connect permission so that others can access the server.

Using below script, you can easily identify those permissions which are important for connecting SQL Server. I took the reference from this official page.

SELECT 
	EP.name, 
	SP.STATE,   
	CONVERT(nvarchar(38), suser_name(SP.grantor_principal_id)) AS GRANTOR,   
	SP.TYPE AS PERMISSION,  
	CONVERT(nvarchar(46),suser_name(SP.grantee_principal_id)) AS GRANTEE   
FROM sys.server_permissions SP, sys.endpoints EP  
WHERE SP.major_id = EP.endpoint_id  
ORDER BY Permission,grantor, grantee
