Anyone having trouble w/ Fedora Core 9?

I've installed it on about 20 PC's and it's been nothing but trouble.
Strange stuff, like:
* The symbolic links between /etc/init.d/sshd a/d /etc/rc?.d suddenly
missing
* The symbolic links between /etc/init.d/network a/d /etc/rc?.d
suddenly missing
* CUPS service suddenly not running
* Missing gtk library (had to re-install gtk2-devel)
* Machines mysteriously hanging

Is FC9 a flawed distro?
