Command line to map webDav-drive?

My current command line is:

net use z: \site.com@5005/p /user:user user

With it i can successfully log on and view the contents of the share, but the files don’t behave right and are not copy-able. All is well if i use a utility to map the drive.

What would be the right command line?
