Probably found the DC by the SRV-rr you have in DNS.

In order to get a krb4 ticket from a krb5 ditto (that is want -4 means) you
need to have support in the kerberos server, running on port 4444.

I guess that you have krb5 ticket, but no krb4, is that right ?

What are you trying to do. Get a krb4 ticket directly ?
