Windows Server DNS not updating

Windows Server DNS not updating
I recently brought a windows 2016 Server into my network. This server was originally configured on a different Subnet but in the same domain. I have already statically assigned a new IP in my subnet.  The problem is the DNS record is still holding on to the old IP. So far this is what I have tried:
Check my network settings and DNS Suffiix.  Ran: (Ipconfig /registerdns)  and (Ipconfig /flushdns) and
I removed the server from the domain and added it back.
I check my Event logs and I do see that my DNS request is getting rejected but I’m not sure if it’s getting rejected from the DNS Server side. I don’t have admin access to the DNS Servers to see if the request is coming from the server with the problem. Here is the error I got:

The system failed to register host (A or AAAA) resource records (RRs) for network adapter
with settings:  Adapter Name : {K8A99A7D-48A1-5343-A82D-CDE738DD9A3D}
           Host Name : test-Server2K16SA
           Primary Domain Suffix : ABC.com
           DNS server list :
               X.X.X.X, X.X.X.X
           Sent update to server : <?>
           IP Address(es) :
             (New IP address)

The reason the system could not register these RRs was because the DNS server contacted refused the update request. The reasons for this might be (a) you are not allowed to update the specified DNS domain name, or (b) because the DNS server authoritative for this name does not support the DNS dynamic update protocol.

To register the DNS host (A or AAAA) resource records using the specific DNS domain name and IP addresses for this adapter, contact your DNS server or network systems administrator. Any thoughts?

Thank you

Thank you for your help!! I Both of the answer were great solutions, the problem is I am in a environment that I have little access. I had been asking them to update the A records from the start but they made me waste time trying to prove that the issues was not on my side. But after 5 days the finally listen to me. LOL
