Hi all,

After install DNS, DHCP on windows server 2008 the vista clients get ipv6 and can't find the exchange server ( exchange 2007 on OS server 2008) .

Open DHCP mmc.

Control Panel -> Administrative Tools - DHCP

Expand your server name. You should see IPv4 and IPv6, depending on your initial setup. Right click on IPv6 and click disable.

Hope this helps.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

sorry , but there is no disable option.

Oh yes, sorry about that. You have to run the DHCP Configuration Wizard to disable IPv6.

From MS website:
Q. How do I disable IPv6 in Windows Vista and Windows Server 2008?
A. Unlike Windows XP and Windows Server 2003, IPv6 in Windows Vista and Windows Server 2008 cannot be uninstalled. However, you can disable IPv6 in Windows Vista and Windows Server 2008 by doing one of the following:

"In the Network Connections folder, obtain properties on all of your connections and adapters and clear the check box next to the Internet Protocol version 6 (TCP/IPv6) component in the list under This connection uses the following items.
This method disables IPv6 on your LAN interfaces and connections, but does not disable IPv6 on tunnel interfaces or the IPv6 loopback interface.

" Add the following registry value (DWORD type) set to 0xFFFFFFFF:

This method disables IPv6 on all your LAN interfaces, connections, and tunnel interfaces but does not disable the IPv6 loopback interface. You must restart the computer for this registry value to take effect.

For additional information about the DisabledComponents registry value, see Configuring IPv6 with Windows Vista.

If you disable IPv6, you will not be able to use Windows Meeting Space or any application that relies on the Windows Peer-to-Peer Networking platform or the Teredo transition technology.

In Windows 2008 there is not such thing like "Right click on IPv6 and click disable." !!!
The accepted answer is not valid.  Follow my step (from MS website) to disable IPv6.
