Enable IPv6 on card and try again.

Check the DNS settings on your server. Make sure it is pointed to a valid DNS server.

ipv6 is enable and I checked dns settings and it's pointing to default gateway router.
is there service pack i need to apply?
Is the Active Directory service running?
Yes active directory is running.
OK, so I decided to reinstall server 2016 which I did and then active directory worked fine. then I decided to move the server from the network and hooked it up to a 5 port switch which is not connected to the network and now active directory stopped working again.??? so once I've setup the server in one network I can't move it to another network???
I am making the assumption that the server is not a domain controller.
The error basically means it cannot resolve Active directory domain services. Can you resolve the DNS to your domain controller from the other network. also check the firewall on the DC allows connection from the other network.
hi Robert yes it is a domain controller and I created users under AD and once I moved it to just a switch I was no longer able to open AD.
If the server in question does not have access to the other domain controllers then you would need to seize the FSMO roles on the server in question as it can no longer contact the role holders.
Just be sure to not plug it back into the a production network after doing so.

Can I disable DHCP and DNS ON THE SERVER? I have a router who handles that. Let me know thanks
This is crazy just because I moved to an isolated switch AD stops working and now the server takes up to an hour to login or restart ???
So if I was to setup this server in a new office and they were to moved the AD would take a dump ??? Doesn't make sense
DNS is a must of Active directory, so you just can't do that.
DHCP yes you can disable it but you need to enabled somewhere else 1st.

It doesn't have any sense to move AD to an isolated network or created it in one place to put it in another.
thanks a lot all is working now
