DC seems to have fallen off the Domain

Scratch that. Its fixed. Thanks @Dashrender. That article led me to the right answer and cause of action.
I don't have a firewall on this server, but the conflict in AV's is what caused the issue and trying to keep the system secured.

It's not uncommon for Symantec products to not fully or correctly uninstall

I'm seeing that with another DC. This other DC is working correctly, but I want to get Symantec off of there before it gets to be too big of a problem. Considering using CleanWipe but not sure if I should or not.

If you're DC is just a DC - you can demote it, then leave the domain, wipe and reload it, join the domain and promote.
If it's also a fileserver, etc, well - have fun.
This of course assumes you can't use the normal tools to remove the old AV cleanly.
-
@nerdydad is this a VM or a standalone server?
-
It's a vm. All of my DC's are vm's.

mkfs.ntfs & format ... The only tools I know to fully remove Symantec products - except for a snapshot maybe.

@NerdyDad Is that secondary domain controller doing anything else like being a file server?

It is a secondary controller. FSMO roles are on another DC. The only other thing this server does is ots a print server and DHCP server.

Well, as I said, if you can't remove the old AV using the typical tools, you do have other options, not great ones, but they are there.

As I am digging into this more and more, I am finding replication issues between DC's, namely the original problem child.
