Do you have 
DOMAIN.NAME = {
kdc = pdc.domain.name:88
...
}
In your krb5.conf?  Is your firewall allowing traffic to/from on port 88? Or do you have 
dns_lookup_kdc = no
in your krb5.conf file? (the default is supposed to be "yes")
And can you ping the kdc from your box?  Is DNS resolving properly?
