404 Error After Successfully Logging in to OWA/ECP in Exchange 2013

Hello,

My apologies first if this would be better asked in another forum but this one seems to fit best.  I am running Exchange 2013 on Windows Server 2008 R2 Standard and am experiencing an issue after logging in to ECP and OWA.  After entering my credentials (all credentials experience the same issue) I am redirected to a 404 error for both \ecp  and \owa.  The odd thing is that Re-entering the url completes the login.  How do I fix the appearent lack of the login.aspx?  If my description isn't sufficient please let me know.

Thanks.
