I Installed DNN 04.08.02 on Win2003 & SQL 2005 Enterprise Edition.
But When I add a links mod to a portal,error occured:

Error: LinkTest is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Value cannot be null. Parameter name: connectionString ---> System.ArgumentNullException: Value cannot be null. Parameter name: connectionString at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteReader(String connectionString, String spName, Object[] parameterValues) at DotNetNuke.Modules.Links.SqlDataProvider.GetLinks(Int32 ModuleId) at DotNetNuke.Modules.Links.LinkController.GetLinks(Int32 ModuleId) at DotNetNuke.Modules.Links.Links.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

Some guys said,the connection string can not have ";",what's it mean?

The connection string in web.config is:

  <connectionStrings>
    <!-- Connection String for SQL Server 2000/2005   -->
    <add name="SiteSqlServer" connectionString="Data Source=sqlsrv;Initial Catalog=DotNetNuke;User ID=DotNetNukeAdm;password=abc123;" providerName="System.Data.SqlClient" />
  </connectionStrings>

  <appSettings>
    <!-- Connection String for SQL Server 2000/2005 - kept for backwards compatability - legacy modules    -->
    <add key="Server=sqlsrv;Database=DotNetNuke;uid=DotNetNukeAdm;pwd=abc123;" />

I don't know how to change it without ";".

Thanks for any help
