Environment

VMware Cloud Director Availability 4.7.3
Microsoft Azure infrastructure

Cause

This issue occurs because an account with insufficient privileges attempted to repair the replication task, leading to a permission denial when trying to establish the NFC connection to the ESXi host.

Resolution

1) Ensure you are logged in or executing commands with a user account that has the proper administrative privileges.
2) Open your PowerShell console.
3) Execute the Repair-LocalReplicator command, specifying the individual VM names of the replicator appliances.
