Named Instances

During the install SQL 2000 askes to use the default to name a instance. I
s
it better to name the instance or use the default? What is the function of
instances in SQL?Hello,
With Microsoft SQL Server 2000, you have the option of installing multiple
copies, or instances of SQL Server on one computer. When setting up a new
installation of SQL Server 2000 or maintaining an existing installation,
you can specify it as:
A default instance of SQL Server.
This instance is identified by the network name of the computer on which it
is running. Applications using client software from earlier versions of SQL
Server can connect to a default instance. SQL Server version 6.5 or SQL
Server version 7.0 servers can operate as default instances. However, a
computer can have only ONE version functioning as the default instance at a
time.
A named instance of SQL Server.
This instance is identified by the network name of the computer plus an
instance name, in the format <computername>\<instancename>. Applications
must use SQL Server 2000 client components to connect to a named instance.
A computer can run any number of named instances of SQL Server
concurrently. A named instance can run at the same time as an existing
installation of SQL Server version 6.5 or SQL Server version 7.0. The
instance name cannot exceed 16 characters.
The maximum number of instances supported in SQL Server 2000 is 16. For
more information, refer to the following articles:

change as well. What I'm doing is replacing are existing SQL server with a
new SQL Server. I've named the new server newsql and made it a member of a
workgroup. After I move the databses over I would then change change the
name on the old server and then make the new server the name of the old
server and join it to the domain. Will the instance name chnage when the
server's name changes?

>|||Hello,
After renaming a server, we can perform the following steps to rename SQL
server instance:
1. Restart the server and then start the SQL Server service. This should
automatically get the *new* Server name and we only need to run the
following procedures to
update syservers system table:
-- For a default instance
EXEC sp_dropserver ''old_name''
GO
EXEC sp_addserver ''new_name'', local
GO
-- For a named instance
EXEC sp_dropserver ''original_name\original_instance_name''
GO
EXEC sp_addserver ''new_server_name\instance_name'', local
GO
2. After running the sp_addserver stored procedure, we must restart the SQL
Server service for the change to take effect. The following article
describes this
scenario in more detail:
