We are installing exchange 2007 into a sbs 2003 domain. We will be decommissioning the sbs server when we are done. We have exchangesp2 installed on the sbs server and the 2007 install keeps saying the 2003 exchange version is not sp2. Here is our error message.

Same problem here (although not with SBS). I've been googling for three days to find an answer - no luck. Ideas, anyone?
