Exchange 2013 install Errors


I am trying to install Exchange 2013 into our current Exchange 2007 SP3 environment. I am getting the following errors when I run c:\Users\administrator.DC\Downloads\Exchange2013>setup.exe /PrepareSchema /IAcce

1)One or more servers in the existing organization are running Exchange 2000 or 2003
2)Cannot find the Recipient Update Service responsible for domain

Since I have been with our company, we have allows had 2007. I assume there was 2000 or 2003 before, but I cannot find it anywhere in AD or ADSIEDIT.

Can anyone help me track down this phantom Exchange installation?

Also, the other error about the Recipient Update Service, I have read I can ignore this error, Said correct?

How many domains you have?
Simon Butler (Sembee)ConsultantCommented:
If you run


does it list any servers that are no longer alive?

The RUS bit is easy. You can delete that from ADSIEDIT.
Configuration, Services, Microsoft Exchange, Your Org Name, Address lists Container, Recipient Update Services

Delete the two entries from within there.
