Then install PIA of ADAM with following steps:

To install the primary interop assembly on Windows XP

1. Install the Windows Server 2003 Administration Tools Pack, available for download at http://www.microsoft.com/downloads/en/default.aspx. This download does not include the AzMan primary interop assembly.
2. To install the primary interop assembly, download the Windows 2000 Authorization Manager Runtime from http://www.microsoft.com/downloads/details.aspx?FamilyID=7edde11f-bcea-4773-a292-84525f23baf7&DisplayLang=en. Run the downloaded file, which unzips files (including the AzMan primary interop assembly) into a directory in the \pia folder.
3. From the Windows Control Panel, run the Microsoft .NET Framework Configuration tool, and then open the Manage Assembly Cache option.
4. Use the Add an Assembly to the Assembly Cache option to navigate to the Authorization Manager Runtime Installation Directory\pia folder, and then add the Microsoft.Interop.Security.AzRoles.dll assembly to the cache.
