Windows 2008 ipv6 register dns problem

tfcexpertexchange used Ask the Experts™

Is there a way to stop windows 2008 from registering is ipv6 entry in the DNS?

when I uncheck the register in the DNS (adapter property), it unchecks both v4 and v6 which, after a couple of hours, "deletes" the v4 entry in the DNS...

To completely disable IPv6 on a Windows Server 2008-based computer yourself, follow these steps:

   1. Open Registry Editor.
   2. Locate the following registry subkey:
   3. In the details pane, click New, and then click DWORD (32-bit) Value.
   4. Type DisabledComponents, and then press ENTER.
   5. Double-click DisabledComponents, and then type 0xffffffff in Hexadecimal or 4294967295 in Decimal.

      Note The 0xffffffff value or the 4294967295 value disables all IPv6 components except for the IPv6 loopback interface.


I know that. I don't want to disable it, I just need to know if it's possible to stop the registering in the dns, only for the v6.


IPv6 takes precedence over IPv4.  If you want IPv6 enabled, then you want AAA records enabled.  Only IPv6 clients would 'think' to query them.

So I guess I don't understand the problem.

If you leave it enabled, you need to have DNS support it.

IPv6 is a routing protocol. DNS is an application "routed" protocol.

You are probably having problems with IPv6 because either your router is not compatible with IPv6 or your router is not configured to allow IPv6 as its routing protocol.

There are other fopars you should know about IPv6 before deciding to use it.

IPv6 uses a tunnel to route with. Hence, IPv6 is not compatible with Netbios.

This means you can not map to netbios shares
It also means "My Network Paces" will not populate a list of computers.
It also means that any other netbios features, like distributive file shares, remote procedure call locator, sysvol/netlogon shares, print sharing ect... will not work. That is unless you convert some of these to DNS as well as use WINS to permit routing of netbios broadcasts.


ok' thanks.

Our routers are not ipv6 compatible... which gives us problem between Vista and Exchange 2007 on Win2008

You may have to revert to IPv4 or get a IPv6 router. Vista will, by default, install both IPv6 and IPv4. Then, it will determine what your router is using. Once it determines this, it will choose between IPv6 and V4 as its PREFERRED ROUTING PROTOCOL.
