Exchange 2010 - can't uninstall / can't move forward

Here's the background:
Primary DC is Windows Server 2008 R2
Backup DC and Exchange 2007 server is Windows 2003 R2 SP2

I'm trying to install a new 2008 R2 server with Exchange 2010.  I installed the Exchange 2010 package but typed in the wrong info for "Configure Client Access" information.  I figured that the easiest thing to do would be to uninstall and start again.

It won't let me uninstall because there are some system mailboxes enabled already.  So, I tried to move forward and try to just correct the mistake by hand.  I went into EMC, opened Server Configuration, Client Access.  Outlook Web App (and other tabs) won't load.  The give the error

An IIS directory entry couldn't be created.  The error message is Access is denied.
.HResult=-2147024891  It was running the command 'Get-OwaVirtualDirectory".

Please help me go in one direction or the other.

Thanks!

Dan

Configure Client Access doesn't really do much, I actually skip past that.
Ignore EMC for a moment, are you able to start EMS? Is the account you are running an administrator? Does it have permissions in Exchange as well?

If you look in IIS manager, do you see the Exchange virtual directories?

I am finding several KB articles which say to add the Exchange Trusted Subsystem to the Local Admin group on the 2007 server.  However, I can't do this because the 2007 server is a DC.  There is no local admin group.

Also, I found one article that said to add the ETS to the Default Web Site in IIS and give it Full Control.  I tried that but it did not change anything.

Actually, I just added it to the AD group Administrators (which, I guess, is the equivalent of local admins) and it seems to have worked.  I will test some more and report back.
