Dynamic DNS update of IPv4 addresses does not not in Windows 7

Several months ago, we noticed behaviors incompatible with Windows 7 clients and their entry in DNS Active Directory.

The main problem is that our Windows 7 clients only will be not systematically their IPv4 address in Active Directory DNS by using dynamic DNS (RFC2136)

Initial question:

  • A handful of customers will register its IPv4 address, but it is a minority and most don't (this is the main question)
  • We use the public IP address space.
  • Customers have been constantly recording the IPv6 address for 6to4 in DNS card but not its IPv4 address.

We have disabled the 6to4 map by using Group Policy, because we do not use IPv6 and don't plan to use the 6to4 transition.

Secondary issue:

  • Customers is no longer recording card 6to4 in DNS (good)
  • Majority of customers do not yet record their (bad) IPv4 address.

What I've checked so far:

  • Analysis using Wireshark:

    • Most clients make no request for SOA record and therefore do not try to send dynamic DNS updates.
    • Some customers get the AD zone SOA record and then send the DNS dynamic update to one of the DCs.
    • I see nothing of clearly different on clients who send updates and those who are not.
    • All the other AD related traffic, for example request/response for domain/ldap SRV record looks normal.
  • Settings on the client:

    • The IPv4 adapter "save addresses for this connection in DNS" checked.
    • The primary DNS suffix is the same as our AD domain name.
    • The AD domain name is a COMPLETE domain name.
    • Use us group policy to apply the primary DNS suffix and some connection specific suffixes.
    • Customers do everything they are supposed to; as access to shared resources, printers, etc. - just not update DNS.

I read all of the following, but I'm no further forward:

Does anyone have ideas/tools/scripts which may be able to progress my troubleshooting?

This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

If you give us a link to the new thread we can point to some resources it
