Question Unable to connect Ubuntu to Windows Server 2022 Active Directory Domain

[bussreports]

Hello,

I can ping Ubuntu from Windows Server 2022, but the moment I use nslookup from Ubuntu to Windows AD, it says there's a "communications error."

I've made changes in Ubuntu such as changes to the SSSD config file and ensure that all ports on Windows (ie DNS port 53) is listening

But regardless of changes and ensuring that Forward LookUp Zones in DNS Manager have the correct A records, Ubuntu will not ping or join the AD domain.
