Steps To Rename In SQL

When one changes the name of the computer running the SQL Server, one needs to perform the following steps to ensure that SQL Server also uses the new updated name. 

• First to check whether the SQL Server has the correct name, execute the following query

SELECT @@SERVERNAME                 AS oldname,       Serverproperty('Servername') AS actual_name

• @@Servername gives the computer name that has been set/registered with SQL Server Serverproperty('Servername') provides the newly updated name from windows.

If @@servername,Serverproperty('Servername') results are different then one should update the new name on the SQL Server. To update, follow the steps provided below.

step 1 :- sp_dropserver/sp_addserver

EXEC  Sp_dropserver   'oldservername'EXEC  Sp_addserver   'newservername' ,   'local'

step 2 :- update sysjobs

Applies only for SQL 2k.

USE msdbUPDATE sysjobsSET    originating_server = Serverproperty('Servername')
