Access to rexec is controlled through PAM (Pluggable Authentication Modules).

For a more secure system, root should not be allowed as a user name for any of the "r" commands like rlogin, rsh and rexec.

If you really do need to use rexec with root, you should edit /etc/pam.d/rexec and comment out the line containing

pam_securetty.so


Obviously, you need to be aware of the security implications that accompany this decision.
