$ samba-tool dns query --username=administrator --password=****** \
    larkin26 EXAMPLE.COM @ ALL  > dynamicDNSRecordsToFix.txt
$ cat dynamicDNSRecordsToFix.txt | grep "Records=0, Children=0" | \
    cut -f2 -d"=" | cut -f 1 -d"," | \
    grep -v msdcs > hosts_to_add_and_delete
$ for WORKSTATION in `cat hosts_to_add_and_delete`
 do
   samba-tool dns add --username=adminsitrator --password=******* \
     LARKIN26 EXAMPLE.COM $WORKSTATION A 127.0.0.3 -k yes
   samba-tool dns delete --username=adminsitrator --password=******* \
