Weird Error Log - Ex 2013 Sp1

So, I am having a hard time figuring out why I cant get into ECP. When I login, it throws the invalid password mumbo jumbo stuff. I look into the setup, everything is correct. I even went to the extent of reinstalling windows fresh with nothing on it and still get the same thing. I decided to dig deeper and I found this weird error with OAB in IIS. Can someone tell me exactly what I need to do to fix this? I believe it is causing me other issues such as exchange management shell access denied, etc.
