I have made a mistake then I install Exchange 2007. The installation stop at the end and I cancel it. After that I could not install it because it already in the organization. I have tried everything. Finally I reinstall the hole server and give the server a new name. After that I install Exchange and it look good but now I have two exchangeserver in the organization. One that exists and one thats not. The big problem is all the message about the exchangeserver thats not exists tell me to fix and check why the server not answer. Can anyone help me? I need to delete that server from my organization.

Hello, you can use ADSIEDIT.MSC (from the support tools) to remove the old Exchange server name in the "configuration part", under the Exchange service. => You will find your organization name, your administrative group, your Exchange servers,... Bye.
