You get this error when attempting to connect to an Active Directory using the Application Security Wizard.
Unable to connect to the Active Directory root.
This error and delays responding to the Next and Refresh buttons in the Application Security Wizard most likely mean that Iron Speed Designer does not have proper access to the Active Directory. Proper access means both that you can log into your computer using the domain user name but also Iron Speed Designer and your application can retrieve information from the Active Directory such as the root path, search the Active Directory and perform other standard operations.
Check if other Active Directory utilities such as Administrative Tools, Active Directory Users and Computers; and Administrative Tools, Active Directory Sites and Services can start. If they can’t find the domain or connect to the domain controller, most likely:
Your computer is not in the Active Directory
Your Active Directory is improperly configured, or
You computer is improperly configured
Contact your IT administrator to properly configure your Active Directory.
