Developed a more elegant solution. Just have a policy run this once on
every machine. So far, so good. dscl . -mcxdelete Users/Guest It should
get rid of any MCX preference stored in the Guest account.
You can use the recon app (to do it remotely), or you can do it from the
same machine with "sudo jamf enroll -prompt". I would strongly suggest
reenrollment, as it usually solves most of our issues. Saludos
