This is a problem with the client identity. Please edit /etc/hostname with
the short name, also edit /etc/hosts with the fully qualified domain name of
the machine. Since we have a disjoined DNS space for our AD, I put a line
like the following in my /etc/hosts file
127.0.0.1 hostname.domain.local hostname.domain.com hostname
Test your edits using the `hostname` command. Check both the short name and
the FQDN using the -f flag. You may want to reboot for good measure to be
sure the hostname is changed and sticks through reboots.
Then try to join again, the DNS update should work in that case now that
FQDN of the client now matches the AD domain.
