Hi Conley I see no other way around this problem as renaming a machine hosting Exchange will break Exchange totally. The services simply won't start. The only way to then resolve that issue is to completely uninstall Exchange and reinstall thus losing all your users and their data. You could then theoretically having backed up all the mailboxes from the original Exchange installation to PST files using EXMERGE.EXE restore them on the new machine but there is an issue with that. Namely the amount of space needed to hold the users mailbox data will increase very significantly as single instance storage will be lost. Hope that helps? Please don't hesitate to get back to me if I can help you further. Regards, Paul Lemonidis. ----- Original Message ----- From: Conley P.

Just would me easy keep the same name. Thanks Hi Conley As it stands no. The only thing I can think of is to add a temporary third server. Move all the mailboxes and public folders to it. Decommission and remove all references to the first server. Then build the new (third) server with your new server name. Having installed the third server then move all the mailboxes to it and remove the second temporary server. As I think you can imagine this is far from simple and will take a good deal of time to do. Why do you need to keep the same server name? If you are concerned about having to recreate Outlook profiles as a result of your new server this should not be an issue. If anyone else can shed an more light on this or knows of any third part products (I very much doubt there are any to be honest) that may do it please feel free to enlighten us. Many thanks in advance. Regards, Paul Lemonidis. Conley Shairrick Network Administrator Cross Oil Refining & Marketing, Inc.
