Renaming a sql server

I installed SQL Server 2005 on a machine named "hardName" and then tested the install.   We then made a DNS alias so the machine could be referenced as "easyName."  I have corrected @@servername via
    a) select @@servername
    b) sp_dropserver oldName
    c) sp_addserver newName,local
    d) Bounce the server.
    e) select @@servername  

The question is, how can I correct serverproperty('servername') without changing the machine's physical name?  The system administrators want to reference the computer via "hardName" but the users prefer "easyName."

One of the reasons for this process was because an old machine "easyName" was up during the install and during the migration of databases from "easyName" to "hardName."  Now that the migration is complete, I want to finish renaming the database instance.

except for clusters, serverproperty("servername") is the machines PHYSICAL COMPUTER NAME.


http://msdn.microsoft.com/en-us/library/ms174396.aspx

MachineName:
Windows computer name on which the server instance is running.
For a clustered instance, an instance of SQL Server running on a virtual server on Microsoft Cluster Service, it returns the name of the virtual server.
NULL = Input is not valid, or an error.
Base data type: nvarchar(128)

Brandon,
Is there any way to change what the SQL server sees as the physical machine name?  Is there a registry change that could be made?

No.  That reads the computer name.  But your users don't need to see this so why bother?

One of my colleagues had a problem setting up replication on the new server.  Apparently the rep install process reads both @@servername and serverproperty('servername').  As yet, these two don't match and the replication install fails.

Correct'ish.  The servername comes from srvname in sysservers.  It doesn't have to match, but the srvname has to be valid for replication (no . or - etc.).  That's where srvnetname comes in to play.  You can call the server something else (except "local") in sysservers other than the physical computer name.

@@servername pulls from sysservers where srvid=0.

select @@servername                       -- Looks ok
select * from sysservers                     -- Looks ok
select serverproperty ('servername')  -- Does not give what I want

Then use @@Servername, which pulls from sysservers.  serverproperty('machinename') will return the physical machine name, that's it.
