When I switch to my subdomain, I get the following error:

I did notice that one of the DC was unavailable.

In some google search, it was recommended to enable IPv6. I did that, and now the DC show as online. However, I still get the same error when trying to access our sub domain in AD MMC. I tried rebooting the DC that was initially unavailable but to no avail.

This is all in an effort to try to resolve an issue for our users where whenever we try to change their password and have them change their password, they are unable to. They get a message indicating that their account is locked.

I would check your DNS records,forward lookup zones, IPv6 wont really make any difference

Also you might have issue with domain trust

This problem is still occurring. Since we have five domain controllers that are replicated, I am just pointing to one specific domain controller to do my administration as a workaround. If this is a domain trust issue, what am I supposed to do to resolve it?

Could you run:

Repadmin /showrepl

and

DCdiag /v /c /e

You can use     >test.txt   to save it to files and post results here
