I've set up a testing environment with three servers using VMware. The first server has Active Directory (AD) and DHCP Server installed, along with user accounts for testing. I've configured the DNS settings on the second and third servers based on the first server, and I can log in using the accounts I created. However, I'm having trouble with the DHCP server; it's not assigning IP addresses to the VMs, and they keep receiving APIPA addresses instead. Is there something I've overlooked that could help resolve this issue?

It sounds like your DHCP server might not be authorized in Active Directory. You should check that, because without authorization, it won't hand out IP addresses to clients. Once you authorize it, things should start working!
Have you set up an IP helper on your core switch for those VLANs? Without it, DHCP requests might not be able to reach your server. Also, check if DHCP snooping is turned off for the switch port where your server is connected; it can block DHCP replies.
Good point! DHCP snooping can be a sneaky issue. Definitely check that out!
Make sure your VMs are all connected to the same network or VLAN. If they’re on different networks, they won't get IPs from the DHCP server. You can check if they're connected to the right vDS or vSS in your VMware settings.
Yeah, authorization is usually the first step to troubleshoot. Make sure to double-check your settings!
