I did the suggestion in the related solution and it cut off all network, internet acces for all servers under that domain, including user's PCs.

I thought disabling the firewall would have just turn off all firewalls.
Does anyone know why it cut everything off as well?

In server 2008 R2 when you disable the firewall it restarts the network adapter to stop the service

Ah ok, that makes sense.
So I assume it would have all come back after a few minutes then?

Commented:
I would have said a few seconds after it restarts itself

hmmm, it definitely went down for about 5 minutes.
In the end I had to log onto a local console for the server and set that setting back to "not configured" after a few minutes, everything came back.

You must have changed some settings.  At a default state, meaning after fresh install onf Windows server 2008, if I turn off the firewall everything still works.  You'll have to check the "local security policy" settings.

I've been using Server 2008 R2 for the last year the problem is I've only disabled the firewall once.
I remember it kicking me off my RDP connection then I set a ping server -t waited for it to come up and it worked fine.

Disabling the firewall service will cause network communication issues.
