Hello, Had you previously had an Exchange server that crashed or was abruptly removed from the domain? Are you installing Exchange 2013 Beta? It looks like you have a deleted lingering object. You may had to use LDP.exe. The link below has (at the bottom) details on how to find the object using LPD. http://technet.microsoft.com/en-us/library/bb288907%28EXCHG.80,printer%29.aspx If this is a production environment, make sure you back up AD prior to the LPD edit.

So you've never run Exchange in your network or attempted to install it before? Because there are references to an existing Exchage installation in Active Directory (Configuration partition). Did you find the entry that is supposed to be removed? What did not work? Could not find? Could find and deleted but still having a problem? EDIT - ok, see you just posted a couple minutes ago with solution. Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you.
