The password cache is full. 

Network Device Enrollment Service stores unused password for later use. By default, passwords are stored for 60 minutes.

Use one of the existing passwords. If you cannot use an existing password:

  • Wait until one or more existing passwords expire (by default passwords expire 60 minutes after they are created).
  • Restart Internet Information Services (IIS).
  • Configure the service to cache more than 5 passwords.
