Recommendations on integrating BIND and AD

[Jonathan de Boyne Pollard]

MD> Actually, this is backwards.  

But your "clarification" is no better.

MD> MS server improperly removes DDNS. 

That sentence makes no sense.

MD> MS OSs don't properly remove entries they have made once they 
MD> are no longer needed (AD DHCP doesn't add clients, they
MD> self-register).

Whether Microsoft DHCP clients perform the Dynamic DNS updates themselves or 
whether the Microsoft DHCP server performs them on behalf of the clients is 
configurable at the Microsoft DHCP server.  It can be done either way.  
Microsoft DHCP clients perform Dynamic DNS updates, if they are the ones 
configured to do so, at both lease grant and lease revocation.

MD> MS DNS servers assume that clients don't clean up after
MD> themselves,

... (which of course they don't when people unplug their laptops and walk 
away or simply switch their machines off at the end of the day - alas) ...

MD> and drop all DNS entries made dynamically.  

This, too, is configurable.  Moreover, "aging and scavenging" is 
disabled by default.

MD> MS OSs assume the DNS server is going to silently discard their 
MD> DNS entries [...]

False.

MD> I have a completely ISC DNS/DHCP shop with AD.

... which possibly explains why you don't have an accurate understanding of 
Microsoft's DHCP server, DHCP clients, DNS clients, and DNS server.
