Windows Firewall – Error Code – 0x80070422

I stumbled across this error when looking, well at another issue, for some reason I wasn’t able to enable the Windows Firewall.

I’m unsure how this happened as there wasn’t anything major wrong with the server, anyhow the fix was pretty simple I only needed to restart the Windows Firewall service. (I wouldn’t usually create a blog post just for this but I think it’s worth a mention, just encase it happens again.) Once this was done the server was happy again.
