using web.deploy.cmd with UNC updates my local files and not server

I'm having issues with web deploy and trying to figure out how to get the web.deploy.cmd to update remote files.  Here's the command I'm running:

web.deploy.cmd /Y /M:\\servername\C$\physicalPath -allowUntrusted /U:\AdminUserName /P:password /A:Basic

Every time I run this from my local machine, it updates my files at the physical path location and not the server.  All the credentials are right.  I'm not getting any error messages, it just updates the wrong computer.

Any ideas on what I'm doing wrong?
