Rather than manually copying files from \\tsclient\some\path to c:\inetpub\wwwroot\webdir I wanted to write a small batch file using xcopy and /exclude to deploy web application files.
However, even when starting the .cmd from a command line in administrator mode, I received an “Access denied” message for each file to be copied due to User Account Control prohibiting write access.
As it turns out, the task can be successfully performed using robocopy with the /zb (or /b ?) switch. (Use robocopy /? to find the huge collection of switches.)
Consequently, the feature known as xcopy deployment should therefore be renamed to robocopy deployment😉
