Exchange 2003 rename SITENAME

what are you referecing when you are talking about site name? Exchange 2003 no longer uses sites, it uses Routing Groups and Admin groups. Are you refering to the organization?

If you are talking about rename the Whole Windows Domain name to something else...  then yes, there is a way to do it, but totally not recommeted.  If you want to rename the domain, you should create the new domain on the new server, trust the old domain servers, move mailboxes, then remove the trust and the old servers.

FYI, to rename the domain:

This is the Exchnage 2003 SITENAME.

windows support tools
start run adsiedit.msc

configuration container
cn=configuration
services
ms exchange
cn=sitename(OrganizationalUnit)

I believe the main OU is the domain name.  Any OU under that you can change through AD user and computer

I doubt your old Priv1.edb and Pub1.edb would mount once you change the Exchange Site name (i.e First Admin Group)
Be carefull, before you do that.
Remove the server from Network or else, the change would replicate and your entire Exchange can do down.

you can simply rename the AG, but any backups done prior to this change won't be able to be restored and started to the new AG name. The legacyexchangedn.exe tool can help you with this change, it's on the E2K3 cd.

Kidego-- this is an admin group and not the org name?

The path he listed above was
Adsiedit
configuration
Services
microsoft Exchange
Sitename

Ater the Microsoft Exchange
is Cn- Active Directory Connections and
Cn= organizational name
if you pierce lower you will have the admin groups.

I am misunderstanding this users question?

I used adsiedit.msc to browse to the sitename and changed it... "CN=ORIGINALSITENAME" to "CN=NEWSITENAME". When I restarted systems manager, it updated to the new site name.
