Trying to install an Exchange Server 2007 into a Exchange 2003 environment and having trouble during the prerequisite check.
Getting the following message during setup:
"Hub transport role prerequisites. Error: Setup cannot continue because one or more SMTP/Send connectors have invalid settings. The value [IP address x.x.x.x] is already present in the collection."
At this point I cannot go any further. I do have an SMTP connector with that address on the Exchange Server 2003. Need help to get past this situation. The server I am using for the installation is Windows server 2008 R2. Thanks in advance...
