asp.net login control doesnt work

I put a login control and it wont let me inside the site. (I even tried to use login control to retrieve and reset password. still wont work).

Here is a section of my web.config file. Yesterday, i fixed that issue by changing the properties in the add tag..but today the problem repeats itself.

     <add name="YourGuruDB" connectionString="Data Source=DIMA-00AA1DA557;Initial Catalog=model;Integrated Security=True"/>
        <add name="modelConnectionString" connectionString="Data Source开发者_JAVA技巧=DIMA-00AA1DA557;Initial Catalog=model;Integrated Security=True" providerName="System.Data.SqlClient"/>
        <add name="LocalSqlServer2" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename='D:\Documents and Settings\Dima\My Documents\Visual Studio 2010\WebSites\WebSite10\App_Data\ASPNETDB.MDF';Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>


  </connectionStrings>
  <system.web>



    <membership defaultProvider="MyMembershipProvider">
      <providers>
        <clear/>
        <add
          name="MyMembershipProvider"
          type="System.Web.Security.SqlMembershipProvider"
          connectionStringName="LocalSqlServer2"
          minRequiredPasswordLength="2"
          minRequiredNonalphanumericCharacters="0"
          maxInvalidPasswordAttempts="1000"
          passwordAttemptWindow="1000"
          />
      </providers>
    </membership>

    <roleManager enabled="true" />

    <authentication mode="Forms">
        <forms name="MyAppCookie"
             loginUrl="~/Registration.aspx"
             protection="All"
             timeout="30" path="/" />
    </authentication>

Does "LocalSqlServer" exists as connection string? What errors are you getting?

You should find in your ConnectionString section something like:

 <add name="LocalSqlServer" connectionString="<YourConnectionString>" providerName="System.Data.SqlClient"/>

And did you enabled FormsAuthentication?

  <authentication mode="Forms">
     <forms loginUrl="<YourLoginPage>" timeout="2880"/>
   </authentication>

Are you resetting the password or being emailed your actual password? Have you checked the Membership table to make sure that you have not been locked out?

I can see you have maxInvalidPasswordAttempts="1000" but if you have been playing about with the config the maybe you locked yourself out before changing the settings.
