can you please inform me the localhost address because in normal case this wasn't happend but if you use some port with local host like this localhost:8989 then the links will not work that i have face in my last expirence

well if you did not use any port then do the fresh installation like this

1. open the web.conf and change the connection string like this close the first one by default its open

 <connectionStrings>
    <!-- Connection String for SQL Server 2005 Express 
<add name="SiteSqlServer" connectionString="Data Source=.\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|Database.mdf;" providerName="System.Data.SqlClient" />-->
    <!-- Connection String for SQL Server 2000/2005-->
    <add name="SiteSqlServer" connectionString="Server=(local) or serverid;Database=databasename;uid=userid;pwd=Password;" providerName="System.Data.SqlClient" />
      </connectionStrings>
 

2. same like this change this

 <appSettings>
    <!-- Connection String for SQL Server 2005 Express - kept for backwards compatability - legacy modules  
    <add key="SiteSqlServer" value="Data Source=.\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|Database.mdf;" />-->
    <!-- Connection String for SQL Server 2000/2005 - kept for backwards compatability - legacy modules -->
    <add key="SiteSqlServer" value="Server=(local) or serverid;Database=databasename;uid=userid;pwd=Password;"/>

after that start the installation then its work make sure you must create the db manually
