Domain Controller Requires SRV record


I am using IPFire as my DNS server. I created a host entry for my Domain Controller however when joining a computer to the domain I get this error:


I am guessing I need to create a SRV record somehow?

I did this by creating a file domain.conf in /etc/unbound/local.d

And I added:

    local-data: " 3600 IN SRV 0 100 389"
