You posted this:

host -t SRV _ldap._tcp.pdc._msdcs.mad.mater.int
_ldap._tcp.pdc._msdcs.mad.mater.int has SRV record 0 100 389 
_ldap._tcp.pdc._msdcs.mad.mater.int has SRV record 0 100 389 
_ldap._tcp.pdc._msdcs.mad.mater.int has SRV record 0 100 389 

Which clearly shows you have three records for the PDC_Emulator DC and 
like that FSMO role, there can only be one, the DC that holds the role, 
you should delete the two incorrect ones.

I have two DC's and this is the output from my domain:

host -t SRV _ldap._tcp.pdc._msdcs.samdom.example.com
_ldap._tcp.pdc._msdcs.samdom.example.com has SRV record 0 100 389
