Rcp is not installed or enabled by default, as it's pretty insecure. Unless you're on a highly trusted local network and need rcp for some particular reason, you should use scp (secure copy) instead. The semantics are the same as rcp.
Further to that btmiller said, to be able to scp to a server, that server must be running an ssh server. On Ubuntu & Debian systems, you need to install the openssh-server package. Not sue about the package name on other distros.
It is not typical for sshd to be running in most default configurations.
sshd and related programs provide an effective, secure replacement for the r-tools - rcp, rexec, rsh - and should be used in preference to them in most situations.
