title: copy-item With Alternate Credentials
body: <p>I'm using the CTP of powershell v2. I have a script written that needs to go out to various network shares in our dmz and copy some files. However, the issue I have is that evidently powershell's cmdlets such as copy-item, test-path, etc do not support alternate credentials...</p>
  
  <p>Anyone have a suggestion on how best to accomplish my task..?</p>
