Group policy editor error

[Simcfc73]

Evening,

 

I'm having a bit of a mare. For some reason the firewall keeps coming on even when I remove it from the group policy on some of my servers... Including new ones.

 

When I went into GP to create a new one I cannot open th windows defender firewall tab snap in. Picture attached 

 

Anyone else seen this. 

 

Also, I can't remember if I ever saw this but when I look at status section in group policy management and do a tldetect now it shows the other DC's symbol as inaccessible... I connect to the other one and it says the same about this one.

 

It's a inherited domain so I'm finding stuff all the time.

Actually, it's the sync that's faulty between the DC's which is causing me massive headaches. DC2 is a 2019 core.  I added a new DC but the sysvol didn't sync on that at all so theres fundamental issues.. I tried all the repairs I could not realised 1 and 2 were faulty.

 

I miss my old network that I built.
