"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Only if ipv6 is the only protocol your network uses.

No it will not cause damage (assuming IPv4 is working as suggested above), but it is pointless to remove it as keeping it does not cause any issue. Just leave it there.

Disabling IPv6 has caused problems for many people in the past.  I do not recommend it unless you have a good reason to do so.

Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

I wouldn't

“It is unfortunate that some organizations disable IPv6 on their computers running Windows 7, Windows Vista, Windows Server 2008 R2, or Windows Server 2008, where it is installed and enabled by default. Many disable IPv6-based on the assumption that they are not running any applications or services that use it. Others might disable it because of a misperception that having both IPv4 and IPv6 enabled effectively doubles their DNS and Web traffic. This is not true.

From Microsoft’s perspective, IPv6 is a mandatory part of the Windows operating system and it is enabled and included in standard Windows service and application testing during the operating system development process. Because Windows was designed specifically with IPv6 present, Microsoft does not perform any testing to determine the effects of disabling IPv6. If IPv6 is disabled on Windows 7, Windows Vista, Windows Server 2008 R2, or Windows Server 2008, or later versions, some components will not function. Moreover, applications that you might not think are using IPv6—such as Remote Assistance, HomeGroup, DirectAccess, and Windows Mail—could be.

Therefore, Microsoft recommends that you leave IPv6 enabled, even if you do not have an IPv6-enabled network, either native or tunneled. By leaving IPv6 enabled, you do not disable IPv6-only applications and services (for example, HomeGroup in Windows 7 and DirectAccess in Windows 7 and Windows Server 2008 R2 are IPv6-only) and your hosts can take advantage of IPv6-enhanced connectivity.”

I would disable it if and only if it's causing issues to begin with, but bear in mind the warnings that Shaun has posted. In business environments I've worked on, it's tended not to matter.

It has not caused problems on our client machines or servers. If it is causing you an issue, perhaps post what the issue is.

To me this falls under the catagory "just because you can doesn't mean you should" - There have been sporadic questions here where the problem was someone who disabled IPv6 because they weren't using it - only they were, they just didn't realize it.  Take Shaun Vermaak's comment to heart and don't do it just because you think you can.
