So I am learning windows server administration and this issue is giving me headache from 3 days.

My setup – VMWARE for hosting this machine on my physical laptop.

VM1- Windows Server 2022 with AD, DNS , DHCP(Enabled) – 192.168.1.2 (DC static IP)

VM2 – Windows Server 2022 with AD, DNS , DHCP(Disabled) – 192.168.1.3 (DC static IP)

VM2- Windows 10 Pro User machine – Set to auto receive IP and has proper DNS servers mentioned.

The scope I mentioned in DHCP1 is 192.168.1.10 – 192.168.1.128
And the address is being leased to the user machine if you see the image below –
Address leased image ss

But on the user machine if I type Ipconfig /all it has an Ip from localdomain 192.168.18.129 instead of 192.168.1.10

ipconfig/all on user machine ss

Now if I ipconfig/release and ipconfig/renew it will give me this error on the user machine –
An error occurred while renewing interface Ethernet0 : The name specified in the network control block (NCB) is in use on a remote adapter.
The NCB is the data.

And here is the wireshark dhcp capture logs during this period –

wireshark ss

Somethings which I have already tried, reinstall DHCP , disabled failover and unauthorized the other DHCP server. Subnet mask is 255.255.255.0 , I don’t know what else to check, ChatGPT and Gemini are both hallucinating.

The VMWare setup for network is using NAT and earlier it worked fine I was able to assign ip’s I don’t know suddenly what went wrong.
