Get-EventLog errors when running in a domain environment

I found this script on this site and it works well when I run it locally but when I run it in a domain environment I this error.  Tried everthing I found on this site and others to no avail... I have full access to the domain and there is a full Trust between my domain and the other.  I can connect to the other computer via EventViewer but when I try and access the Application log I get the error of Access denied... if you look down the second block of code works when running from a .bat file using task Scheduler.  i'm lost here, why would one code work and the other not? is there a way to use credentials in powershell?
