yep, there are your problems!!
Look at your DNS entries. You can only use Windows DNS servers for DNS to have this problem solved.
It also appears that you are not using DHCP - why not?
Also, why is 127.0.0.1 in that list? that is basically saying, use myself to find DNS information, but non of your PCs have a DNS sever installed on them, I hope.
What is that ::1 in DNS servers?
That is IPv6 loopback

Oh I see. Thanks

Do you have someone else in the company who is a senior IT person? Or are you the one currently in charge of the network?

there is a senior IT person. But he is at the same level as me when it comes to DNS

The only DNS IPs that should be listed in any PC that lives on your network should be the IPs of these machines
Im aware of that

Hold the phone here -
JB pointed out to me that the ipconfig you posted is from your DC.
THAT majorly changes things.
You can point to yourself for DNS on a DC - in your case you don't need to, because have 6 DNS servers.
You need to change the Domain Controller's DNS to all point to other DNS servers on your network. The primary one should point to another Local DNS server if there is one, the secondary can be local or remote. If there are no other local DNS, you have no choice but to have the primary point to another DNS that is remote.

Yeah I was literally just typing that out in a post. Rose-DC1 so it would refer to itself for DNS

I'm really thinking JB is right, you need to hire someone to either remotely assist you or come onsite and give your network a good once over. it will be well worth the spend.

128.1 is the only DC/DNS on site so its pointing to 118.5 which is a DC/DNS server at a remote site. -
what is the name of that server at that site?

The DNS setting in the NIC for a DC (assuming it is also a DNS server) should ALWAYS point to itself first.
It should never point to anything else first.
DNS 1: 127.0.0.1
DNS 2: Some other INTERNAL DNS server -

DNS 2: Some other INTERNAL DNS serverOnce you have that setup right, everything in the local office will immediately start working right.
Next, you need to look into your DNS configuration, because in theory, you should have still been working if your DNS was properly replicating between all of your servers.

What DNS addresses are your clients getting from DHCP?

we dont use DHCP. Clients are statically assigned 118.5

DNS 1: 127.0.0.1
DNS 2: Some other INTERNAL DNS serverOK I'll disagree here. A DC should always point to another DC first and itself second. The assumption is that the other DC will be up and running while this DC is down. This will allow this DC to boot up faster on the assumption that DNS isn't the first thing that comes up.
I have seen faster reboots because I point to some other DNS server instead itself first.

While I don't understand your lack of use of DHCP, that shouldn't really matter.
The clients do need to have DNS entries of only DNS servers within your network, they should never have an DNS entry for something outside your network, like google's 8.8.8.8 or your ISPs DNS servers. That will cause all kinds of problems.

Microsoft agrees with you, but I have dealt with too many issue like this to like that answer.
Faster or slower is not really relevant. If you are relying on DC reboot speed for anything in your network, you have some other issues.
Relevant to the topic, his DNS is obviously hosed because it is not resolving right. So set it to 127.0.0.1 first and then secondary to the other DNS server. make sure everything works, then figure out what is going wrong with DNS replication.
Once that is then resolved, you can change the DC to point to the other first again.
