Hi eg10013, System.DirectoryServices.AccountManagement is supported on Windows XP, Windows Vista, Windows Server 2003, and Windows Server 2008. What server you are using? Please refer to the following link about it: http://richardspowershellblog.wordpress.com/2008/05/25/system-directoryservices-accountmanagement/ And here is a article about how to process Active Directory information in SSIS: http://social.technet.microsoft.com/wiki/contents/articles/processing-active-directory-information-in-ssis.aspx If you have any qeustion, please feel free to let me know.

Thank you for your response. I tried to use the following code to get user's email address so I need to reference System.DirectoryServices.AccountManagement . I am working on a Windows 2008 (sp1) server. PrincipalContext ctx = new PrincipalContext(ContextType.Domain, "dcname"); UserPrincipal u = new UserPrincipal(ctx); u = UserPrincipal.FindByIdentity(ctx, UserName);
