samba_dlz: disallowing update of signer=WIN7-PC\$\@SAMDOM.EXAMPLE.COM

No, none like that. I see other samba_dlz entries of a positive nature. 

Thoughts? (Could this have anything to do with my recent dns issue? Is
some record missing?)

by the way, did you create the reverse DNS zone on your DC? The PTR are 
properly registered by client computers on recent samba version, but you 
have to create the reverse DNS zone beforehand.
