I am going back and forth with this issue. They do everything faster. Windows 8. Turn it off and lags for minutes. Drove me crazy. Might just all be in my head but I spent a week on it and there seems to be some truth to what MS is saying on to not disable it.

Internal only. Nothing on the fw is using ipv6. This topic has been locked by an administrator and is no longer open for commenting. Read these next So far I haven't seen anyone saying how we troubleshoot problems with IPv6 other than to shut it off. And when IPv6 does frequently give us problems, shutting it off does solve those problems. So without any other troubleshooting tools, we will continue to shut it off when there are problems.

And we will get it into our routines to shut it off on original install before anyone complains about the inevitable problems. You want us to stop shutting it off. Then don't tell us how great it is. Tell us exact steps and tools to troubleshoot it WHEN it causes problems.

Telling us to stop using our "old" routers and software is not an option. I'm an IT professional who prides himself in trying to learn at least one new thing every single day, so in no way can I be accused of clinging to the "old ways".

However, we get measurably better network performance on all PCs and servers when IPv6 is disabled. Does IPv6 have potential? I believe that eventually we're going to be able to implement it confidently and live happily with it, but we're not there yet as far as my experience has shown.

It is common for IT administrators to disable IPv6 to troubleshoot networking-related issues such as name resolution issues.

We do not recommend that you disable IPv6 or its components. If you do, some Windows components may not function. Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly.

Before you modify it, back up the registry for restoration in case problems occur. Windows use bitmasks to check the DisabledComponents values and determine whether a component should be disabled.

For each bit, 0 means false and 1 means true.
