Using robocopy to copy files from a network share over a WinRS command line session

Question

Hello,
Preface: Using server 2008 enterprise.
I can't seem to get robocopy to function over WinRS and I'm not sure where the problem actually lies.  Running robocopy locally on the computer does work fine, but as soon as I try to run it through a remote command prompt through the WinRS client or directly with the WinRS client I get an access denied message (error 5).
I've tried using runas while logged into the remote command prompt as well, thinking that it could have been some sort of permissions inheritence issue.
I've checked the permissions on the remote file share, I've even given 'Everyone', 'Anonymous Logon' and the computer's active directory account full control over the folder and the file I'm trying to copy, but still get the access denied error.
I've tried using /COPY:DT since I read that usually resolved error 5 issues.
None of these things have worked.
I'm kind of out of ideas, I've read some blogs of people who have written powershell scripts which use winrm/robocopy so I figure I'm missing something stupid.  Or maybe I've stumbled upon a bug?

Answer 1

Yep, I verified permissions on them all :(
To maybe complicate the issue, I looked at the environment variables for myself while logged in locally to the computer and through WinRS and they look to be the same.   
EDIT: Out of pure frustration I wrote a quick console application which impersonates the currently logged in user and copies a file from the network share I'm trying to access to the local computer.  The application properly impersonates the user - but does not copy the files while it's run through WinRM.  When you run the application as a locally logged in user it works just fine.
WinRM must be behaving goofy :(
 This is the output of the following application:
