Yes, you can use simple methods: "rm /usr/sbin/useradd" or "chmod a-x /usr/sbin/useradd". But this only disable, but not deny. root-user can copy "useradd" binary file from another server and set execute bit. SELinux can deny operation useradd even for the root-user. Restart the server, in my opinion, is not required. But the need to restart several services and remounting of file systems. Good luck!

Thanks Dustin! This worked like a charm! Tyurin, I cannot reboot the server right now , so was not able to try the selinux stuff. But I'll try that definitely. Thanks! Rohit Khaladkar.
