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.
