DHCP server showing by IP Address

Hi all

Purely cosmetic issue but it is driving me mad. I have a new Server 2019 core server I am setting up as a DHCP server. It is on the domain, DNS records exist and resolve for it. DHCP role installed and scopes configured. The problem is this:

When I authorise the server it shows as it's IP address in the list of "manage authorised servers" where as all my other servers show as their host name. I can't be having this, I'm twitching.

Any ideas as to why this would happen?

When you authorise it are you doing so via PoSH?

Code:

Add-DhcpServerInDC -DnsName "dhcp01.contoso.com" -IPAddress 10.x.x.x

If so it should show up via the DNS name assuming that it is resolvable via the DNS name.

No, just via the GUI but I will try this now! Thanks.

So I did this and the server is authorised but it doesn't show up in the list of "manage authorised servers" in the DHCP mmc lol. I will give it time, maybe it's replciation related or something.

Can you create a test scope on the DHCP Server? In MMC if you open up DHCP and add the server manually ignoring the authorised servers list can you manage DHCP via that?

Yea. The DHCP server is actually set up as a failover replication partner so it has scopes on it. It authorises fine and works. It's just the name bit that is alluding me.

Had a hell of a day but just checked it now and IT'S DONE IT! Yay, thank you. My OCD thanks you
