Trying to install Exchange 2010. Everything is working okay, but when running Organization Prerequisites It tells me that there is one or more server in the existing organization running Exchange Server 2003 without service pack 2....
Problem is there is not an Exchange server 2003 in AD...but I do remember installing Exchange 2003 on a server, but it no longer exists. It seems that "pieces" of that 2003 install is hanging out in AD making 2010 think one still exists.
Anyone know how to remove the 2003 "pieces" to make this install proceed? or will I have to start over with AD :-(
