Have installed DNN precisely, per Jan Blomquist's (TrainCert Video) instructions.  Got the following error.  I've tried the install several times, undoing previous attempted installs.  Each time I get the error above.  Below is the stack trace:

Format of the initialization string does not conform to specification starting at index 56.

[ArgumentException: Format of the initialization string does not conform to specification starting at index 56.]

Please offer potential solutions.  I'm looking forward to implementing DNN.

I've the same error following install standard instruction (/Documents/welcome.htm). Any suggestion ?

Thanks !

Thanks a lot for your time !

1.) DNN  Version: 4.0.2

2.) Database: Sql Server 2000 running on a different machine

3.) Follow 2 parts of web.config I've modified.

first part:

<connectionStrings>
<!-- Connection String for SQL Server 2000/2005 -->
  <add name="SiteSqlServer"  connectionString="Server=10.12.1.215;Database=DotNetNuke;uid=dnn;pwd=xxx;" providerName="System.Data.SqlClient" />
  </connectionStrings>

second part:

 <appSettings>
    <!-- Connection String for SQL Server 2000/2005 - kept for backwards compatability - legacy modules -->
    <add key="SiteSqlServer" value="Server=10.12.1.215;Database=DotNetNuke;uid=dnn;pwd=;xxx" />
    <add key="InstallTemplate" value="DotNetNuke.install.config" />
    <!--  Alternative Install Templates (included in package)
    <add key="InstallTemplate" value="Club.install.config" />
    <add key="InstallTemplate" value="Personal.install.config" />
    <add key="InstallTemplate" value="SmallBusiness.install.config" />
    -->
    <add key="AutoUpgrade" value="true" />
    <add key="InstallMemberRole" value="true" />
    <add key="ShowMissingKeys" value="false" />
    <add key="EnableWebFarmSupport" value="false" />
    <add key="EnableCachePersistence" value="false" />
    <add key="InstallationDate" value="4/19/2006" />
  </appSettings>

Thank in advance.
