Unable to install Exchange 2013 after having it uninstalled due to previous failed installation

Hi

I have setup a lab where I got windows server 2008 R2 as a DC with windows server 2003 functionality level for the domain, and I installed windows server 2012 R2 then got Exchange 2013 installation on it... I left the installation going and went out of the lab, then next day I noticed that the installation ended with a failure, but some parts of exchange have been installed...

So I ran the uninstall wizard and got it removed without any issues... but when I try to reinstall it again, I do receive error during Readiness Check phase that the user I use is not having the right groups, and the setup was unable to contact the AD server... while I can ping the domain and communicate with it normally...

In the event viewer, I receive the following events:
