Change Server Name in SQL Server

Hello Everyone,  

Today, I have a Requirement to change server the name of SQL Server, After completed this task  going to share the sample query for change the server name in SQL Server.

Some Noted Point Keep in Mind which are given below

1.  If SQL Server is clustered then you should not rename the server name otherwise you rename it.

2.  If you are using replication in SQL Server then can't change server name.

3.  If you are installed the Reporting Service that time you not rename or change the server name.

First you run below query and find the detail about you SQL like Host Name, Server Name, Machine Name, Net BOIS name and last one SQL Server is clustered or not.

 SELECT  HOST_NAME() AS 'HOSTNAME',

                        @@SERVERNAME AS 'SERVERNAME',

                        SERVERPROPERTY('SERVERNAME') AS 'SERVERNAME',

                        SERVERPROPERTY('MACHINENAME') AS 'MACHINENAME',

                        SERVERPROPERTY('COMPUTERNAMEPHYSICALNETBIOS') AS 'NETBIOSNAME',

                        SERVERPROPERTY('ISCLUSTERED') AS 'ISCLUSTERED'

The Steps of fallowing process as given below

STEP 1: EXECUTE BELOW TO DROP THE CURRENT SERVER NAME

EXEC SP_DROPSERVER 'OLD SERVER NAME'

STEP 2: EXECUTE BELOW TO ADD NEW SERVER NAME. MAKE SURE LOCAL IS SPECIFIED

EXEC SP_ADDSERVER 'NEW SERVER NAME', 'LOCAL SERVER'

STEP 3: RESTART SQL SERVICES FOR REFRESH ALL THE STUFF

STEP 4: VERIFY THE NEW SERVER NAME WHICH YOU CHANGED USING THE BELOW QUERY

SELECT @@SERVERNAME AS SERVERNAME

SELECT * FROM SYS.SERVERS WHERE SERVER_ID = 0

The output look like below image.
