Q. Can I rename a server after installing SQL Server 2000?
A: Yes, you can rename a server after the installation of SQL Server
2000. When the SQL Server service starts for the first time after the
name change, it automatically recognizes the change and resets the
computer name. You do not need to run setup again to reset this value.
However, you must perform several additional configuration steps. To
correct the sysservers system table, you should manually run the
following procedures.
For a default instance: sp_dropserver <old_servername>
go
sp_addserver <new_servername> , local
go
