Delegation Issue.

Hello all,
I¹m trying to set up a subzone delegation for a BIND/AD setup following this
article: ³².

I¹m trying to place the ³IN NS² substatement displayed below to establish
delegation to ³² in the main zone file for ³company.com²:

$TTL 10800      ; 3 hours               IN SOA (
                                2006040520 ; serial
                                28800      ; refresh (8 hours)
                                7200       ; retry (2 hours)
                                604800     ; expire (1 week)
                                86400      ; minimum (1 day)
                  _msdcs        IN  NS       86400   IN      A

But when I do this I get errors from Bind when starting named which say:

Starting named: 
Error in named configuration:
zone localhost/IN: loaded serial 42
zone loaded serial 1997022700
pzones/company:11: unknown RR type '_msdcs'
zone loading master file pzones/company: unknown class/type
_default/ unknown class/type
zone loaded serial 2005031787

Any ideas?  This step is used to delegate all AD DNS request changes to back
to the AD servers.  According to what I have read this should work, but as
you can see its not.  : )

Any help would be appreciated.
