Have you ever gotten into the application successfully, or is this a post-installation issue?

Assuming this is an initial installation issue...

Can we see the contents of these tags in your web.config file?

What is your IIS website security setting?

What is your Project startup option (custom or...)

Yes this is an installation issue
>>Can we see the contents of these tags in your web.config file?

<appSettings>
    <add key="CslaAuthentication" value="Csla" />
    
    
    <add key="CslaDataPortalProxy"
            value="EnterpriseServicesHost.EnterpriseServicesProxy, EnterpriseServicesHostcs"/>
</appSettings>

<authentication mode="Forms">
      <forms loginUrl="Login.aspx" name="ptracker"/>
    </authentication>
    <authorization>
      <allow users="*"/>
    </authorization>

>>What is your IIS website security setting?

It's setup to default without any changes

>>What is your Project startup option (custom or...)

It's http://localhost/PTWebcs

Problem is still unresolved.

Sorry for the delay getting back to you - crazy day at the office!

Are you sure you want to use the CslaDataPortalProxy? It's not necessary unless you really want to connect to the database via a com object.

If you *do* want to use the above method, there are some very specific setup instructions in the book to follow. I was able to get that method to work when I followed them.

If you don't want to connect via a com object - my recommendation unless you know why you need a com object :) - just fill in the connect string correctly and comment out the CslaDataPortalProxy entry. My connection strings are for SqlServer, not SqlServer express (which is what is in the sample application).

</connectionStrings>

The above DataSource values assume the system name of your computer is MYCOMPUTERNAME and that you are using the default SqlServer instance. If you created a custom instance of SqlServer, you will need to append \INSTANCENAME to the computer name. (Or maybe it is a / instead of a \. )

hth

constant errors - any thoughts?
