Thanks for replies but I still have some problems : 1- I use the CKS FBAManagement_Beta_1.00 from codeplex but it doesn't work it gets error like registration webpart --> error page when i use FBA setting in site setting --> it gets errors which is A Membership Provider has not been configured correctly. Check the web.config setttings for this web application. 2-does this process need to the steps before runing? 3- do i have to deal with the ASP provider (or membershipe provider) and create new database in sql server? sharepoint 2007 build on sql server can i deal with this database immediately? 4-are there any books or documents talk about this subject(sharepoint 2007 Extranet) in details? Thanks

I haven't use this tool yet but I think before running this tool you have to create a FBA database and configured your web.config file. Follow the steps. 1. Create a membership database for your FBA 2. Extend your web application. 3. Enter connection string, Membership and Role parameter in web.config file 4. Add your Membership and Role name in extended web application. 5. Run this tool. Follow below link to this configuration http://www.codeproject.com/KB/sharepoint/FBA.aspx Hope this will help youCheers, Hemendra-MCTS "Yesterday is just a memory,Tomorrow we may never see"
