I received request from my internal team to provide a small solution on Esxi Domain join and created when pulled it in domain computer account should be created in specific OU (Organization Unit). To perform this task first, we need complete OU path, to find it open Active Directory Users and Computers, on the View menu click Advanced Features. For more on be

POWERCLI AND VSPHERE WEB CLIENT: JOIN ESXI INTO Active Directory DOMAIN CONTROLLER

Next click on the OU where you want to create Esxi Computer Account. Right click on OU and go to properties, You will see an Object tab, (This Object tab is only visible when Advanced features is enabled), Under it find Canonical name of object and copy paste OU path.

On the ESXi server when you try ESXi Join Domain under Authentication services. Use the path in Domain. Once esxi is joined to domain successfully, you will see new Esxi host computer account is created in active directory dsa.msc. If you are seeing an issue check my below article.
