Removing IPv6

A previous network admin installed IPv6 on all servers and workstations on my network.  We're experiencing weird network issues and I'd like to remove IPv6.  What are the repercussions?  Is there an order I need to do this so that I don't kill network connectivity?

I see in Microsoft DNS that there is a Host (A) entry [with IPv4 ip address] and a IPv6 Host (AAAA) entry for every machine.

Can it be done incrementally?  I have a lot of machines and multiple locations, so this isn't going to be done quickly.  I can't kill connectivity while this change is in progress.

If you're running on IPv4 completely now but just want to uninstall ipv6, it won't interfere with anything. Because being installed doesn't change anything if still ipv4 is in place.

Just write a batch script for 'ipv6 uninstall' and let it run as startup script for all computers.

Cheers,
Rajesh

When you say running on IPv4 completely now, do you mean the routers and switches?

Do you have any suggestions on how to script this?  Could it be done via a GPO?

Routers/Switches/Desktops/Servers all of them.

Very simple, write down a batch script with this 2 entries;

ipv6 uninstall
shutdown /r
