We have a domain with 2 2003 servers on it and are attempting to install Exchange 2013 on a 2008 R2 machine. We installed it successfully but they had a myriad of issues with OWA and were not able to fix the issues with that and a few other things. I thought uninstalling and reinstalling Exchange would rewrite possible corrupted files. I was not able to uninstall with the gui so I used the unattended commandline tools to uninstall which worked. Now when I try to install again I am being told that the account I am using is not in the enterprise admin group, the organizational management role group, that there is no organizational management role group, and that active directory does not exist or cannot be contacted. We have confirmed the domain is functioning properly.
Any ideas on how to approach this?
