I'm not sure that I understand what you mean, but DES is disabled on purpose
because it is completely insecure nowadays. Maybe you should try to rule it
out from your deployment.

According to [1], it was possible to attack DES key back in 2008. I don't want
to even guess how easy it has to be today. DES in Kerberos was formally
deprecated by RFC 6649 [2].

Also, -CRC variants are completely insecure by design (because it is malleable).
