I have a Jenkins agent, Windows 2016 Server deployed using ec2-plugin. The issue I'm having is during the build job, I get an access denied error when it tries to copy a file to a DFS share. The strange part is this behavior doesn't happen when I use a different Jenkins agent, using same AMI but deployed using the slave-agent.JNLP.  It's the same build job but on different nodes.
