i have this in my web.config file

<connectionStrings>
<add name="ConnectionStringTest" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Inetpub\wwwroot\sqlSite\App_Data\siteDB.mdf;Integrated Security=SSPI;Connect Timeout=30;User Instance=False"
providerName="System.Data.SqlClient" />
</connectionStrings>
<appSettings />

<system.web>
<!--
Set compilation debug="true" to insert debugging symbols into the compiled page.
Because this affects performance, set this value to true only during development.
-->
<compilation debug="true" />
<identity impersonate="true"/>

and my asp connection string is

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionStringTest %>"
SelectCommand="SELECT [entryID], [compID], [emailAddy], [answer] FROM [entry]"></asp:SqlDataSource>

if i set user instance to true i get a user permission error.

it says on sql server management that i have dbo rights on my database, but it wont let me put datareader or write on this login. any ideas? its driving me insane

Looks like SQL server could not connect you file to system

An attempt to attach an auto-named databasefor file C:\Inetpub\wwwroot\sqlSite\App_Data\siteDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or itis located on UNC share.

so it automatically switched you to master database which is default for new users and probably you have no rights to create table in it.

Is your database file local to your server?

Does you SQL server user accont has rights to access this database file?

Check it.

Thanks

Is your database file local to your server? - yup

Does you SQL server user accont has rights to access this database file? - i only have 1 user account - funkymp which i log onto my computer which, it says on sql management tool that im the dbo for the database

|||

if i go into databases - databasename - security - users i have dbo (which is the funkymp account), guest, info schema, rob\aspnet and sys.

if i go into securiy - logins, i have funkymp there again, default database is master - should i change this to the database im trying to access? this is driving me up the wall had the same error for 2 das now, are there any sql commands that i can run as a new query to check if i have the rights to access that table with the user funkymp?

Hi,

It seems that you might not be connecting to the correct database.

Please try to add Initial Catalog=<DatabaseName> in your connection string.

HTH.
