I did follow the installation procedure for vista but it seems not working on me..

"Error Locating Server/Instance Specified" means that the data source you specified in the DBConn line in the web.config isn't working. Make sure that the information you put there is correct (spelling, name, etc), that the server is accessible (if the DB is on a remote server), and that the instance name is correct. Unless you intentionally set up an instance name, there likely won't be one and you can just specify the servername.
