I am getting Invalid Drive Specification when using xcopy to copy a sharepoint site to a backup location. I am executing the command via cmd window from the sharepoint server itself. I have tried it from another server exactly via cmd line and it works fine. If I execute the command via cmd line on the sharepoint server I get the error. I have WebDav installed on both servers and Webclient service running. I can map a drive from the sharepoint server to the url via explorer and can access the url via "start / run" I don't understand why I cant xcopy from it here. I can from another similarly configured server.
Results from sharepoint server
