I'm running a test environment with three servers on VMware. On the first server, I installed Active Directory (AD) and set up a DHCP Server, where I also created user accounts. The DNS settings for the second and third servers were configured based on the first server. I can log into the accounts created in AD on the first server, but I'm having issues with the client machines not receiving any IP addresses—I'm only getting APIPA addresses. Is there anything else I need to configure to get this working? Any suggestions would be really appreciated!

It sounds like your DHCP server might not be authorized in Active Directory. Make sure to authorize it; once you do, your clients should start receiving IP addresses without the APIPA issue.
There could be several reasons for this. First, double-check that you've authorized the DHCP scope in Active Directory. If that’s already done, it might be something else.
Make sure all your VMs are on the same network and confirm that the network or VLAN is connected to the same virtual distributed switch (vDS) or virtual standard switch (vSS). This can often be the culprit.
Have you set up an IP helper on your core switch for those VLANs? That’s often necessary for DHCP to function across subnets. Also, check that DHCP snooping is turned off for the port the server is connected to.
