Exchange 2010 Client Access Role Installation Error

The image below shows the installation error I am getting when trying to install the CAS role for Exchange 2010, any help would be greatly appreciated.

I have had Exchange 2010 installed successfully before when it was beta, I used the same name "MCC-EXCHANGE-01" as i'm trying to use now if that helps solve this error.

Thank You!!

do you have any exchange 2007 or 2010 server in your environment?
if not:
launch adsiedit
right click and connect to
connect to configuration partition
then browse to configuration - services - microsoft exchange - exorg name - administrative groups

check if there is an exchange administrative group FYDBO

We have our live Exchange 2007 server, but before I did the 2010 installation I went into Administrative Groups in ADSI and deleted the prior MCC-EXCHANGE-01 under Servers, not sure if there is something else in another location that should have been deleted also?

Thanks

I found the solution, since I had a previous installation of Exchange 2010 in my organization I had to open ADSI Edit and go to Configuration, Services, Microsoft Exchange, Your Organization, Administrative Groups, Exchange Administrative Group, CN=Databases and delete the old database references out of the container, once I did this the installation ran successfully!!

I'll give you the points anyway endital1097, thanks for helping :)

thanks, i was preparing for a datacenter move this weekend
i would have said to look at the databases container since 2010 moved the location
