Hi all,

Small business here, I am currently migrating from ESXi to Proxmox.

The last but not least VM to migrate is our Windows Server 2019 with the roles of AD / DNS / DHCP.

The problem is that after having set back IP address on the new virtio network adapter (the esxi one has disappeared as I changed to virtio) the DHCP role does not work anymore. From the server side, DHCP seem OK but no computer can obtain a IP from it. I am really lost, I don't really understand what can cause that.

Firewall is disabled on the VM network virtual adapter. IP / Gateway / Subnet / DNS are correctly set in the VM.

Maybe I am missing some specifics network adapter settings that Windows added when installing these roles ?

I hope someone could help me with that ? I have had to abandon for tonight and start back the EXSi VM for tomorow morning.

Thank for your help.
