thanks for your reply. but i cant run correctly.  i configured asp.net 2.0 my default web site in iis. NETWORK SERVICE and asp.net users have full permission to website folder. i am deleting permissions and reset permissions for network service and asp.net users. but its dont work correctly. its very important for me. i was open project in visual studio for debug project. but i cant run project correctly. how can i run this project corretly. its very important for me wedwardbeck. can u send me iis virtual directory xml file  (using save configuration file in iis for  win2003), your web.config file, your new (empty)database script and your dotnetnuke version?

i am fallowing this way:

• create new database in sql 2005 name of DotNetNuke with owner account. (user222)collution :SQL_Latin1_General_Cp1254_CI_AS
• set up web.config file for sql 2005 permissions as that

<!-- Connection String for SQL Server 2000/2005-->

<add

name="SiteSqlServer"

connectionString="Server=SIMETRI96;Database=DotNetNuke;uid=user222;pwd=123123;"

providerName="System.Data.SqlClient" />

• set up webconfig for application name (same in iis) as that

<add name="AspNetSqlMembershipProvider"

type="System.Web.Security.SqlMembershipProvider"

connectionStringName="SiteSqlServer"

enablePasswordRetrieval="true"

enablePasswordReset="true"

requiresQuestionAndAnswer="false"

minRequiredPasswordLength="7"

minRequiredNonalphanumericCharacters="0"

requiresUniqueEmail="false"

passwordFormat="Encrypted"

applicationName="DotNetNuke_2" (its my application name in iis)

description="Stores and retrieves membership data from the local Microsoft SQL Server database" />

• asp.net and network service users have permission in the all child folders in website folder
• but it isnt work correctly
• my dotnetnuke version is DotNetNuke_4.3.2

if you can help me i blessing for you
