The networkname was changed to 'SQL2K5SWPROD'. But SQL Server was installed after the name change happened. So I reckon this should show the new name for @@SERVERNAME as well.
I tried
sp_dropserver 'SQL2K5SWSRV', null
Command(s) completed successfully.
sp_helpserver
Msg 15205, Level 16, State 1, Procedure sp_helpserver, Line 17
There are no servers defined.
sp_addserver 'SQL2K5SWPROD','LOCAL'
Command(s) completed successfully.
sp_helpserver
namenetwork_name
----------------------------
SQL2K5SWPRODSQL2K5SWPROD
After executing the commands the @@SERVERNAME should be returning 'SQL2K5SWPROD', but the it still returns the incorrect value ['SQL2K5SWSRV']
Any suggestion to get this corrected without a downtime would would be of much help.
Cheers,
Imran.
