So should I just uncheck ? or perhaps not worth the effort and may cause
some other issues if I do uncheck.. My goal is to disable services etc
not required on my DCs and potentially perhaps increase performance ...

thanks..

If it helps, for my customer's DCs and Exchange servers, I usually uncheck
them as well as IPv6, since none of them are using IPv6, as well as
disable IPv6 in the registry, as well as make sure there is no IPv6 DHCP
scope, that is when I create a scope. To me, it's unecessary services, at
the same time there's a known issue with DSAccess communication between
Exchange and the DCs when using Outlook Anywhere (RPC HTTPS).

Here's more info on disabling IPv6:

Disable IPv6

====
There are known issues regarding IPv6 affecting communications in certain
scenarios, such as with errors when using Outlook Anywhere such as to fix
an Exchange/DC NSPI port 6004 communication issue, among many others.
Therefore to eliminiate communications issues regarding whether this is a
factor or not, it is recommended to disable IPv6 in registry on the
Exchange server, as well as on the domain controllers, or any server for
that matter, especially if there are no plans in using IPv6.

To disable IPv6 on 2008 or Vista:

Uncheck IPv6 in NIC properties
Uncheck the two LinkLayer Topology Discovery components
Then follow the registry changes procedure below to completely disable
IPv6.

1. Navigate to:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters]
2. In the details pane, click New, and then click DWORD (32-bit) Value.
3. Type in DisabledComponents , and then press ENTER.
4. Double-click DisabledComponents,
5. Type ff in Hexadecimal.
6. So it should like this when completed:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters]
"DisabledComponents"=dword:000000ff
