Error code 2732: Failed to join the domain while provisioning hosts. This error is related to Windows updates from October 2022 (for details, see KB5020276—Netjoin: Domain join hardening changes). It occurs when a device is joined to a domain by one admin account, and another account attempts to reuse the same host name to rejoin the host to the domain.

This can typically happen during the AVD host re-imaging process when the domain admin credentials, initially defined in Nerdio Manager, have changed since the time the host was originally created.

To resolve this issue, remove the computer objects from Domain Services (either AD or Microsoft Entra Domain Services), and then attempt to re-image or replace the host again.
