Unknown connection option in connection string: initial catalog.

you can get connection string in following way also...
1. create test.udl file on ur desktop.
2. open that file
3. select ur sever name
4. select ur database
5. click on test connection (if its succeded)
6. click on finish.
7. open same file with wordpad/ notepad
8. add username and password(if you are using server authontication)
copy the connection string and pest it your config file

   <add name="ApplicationServices" connectionString="copy connection string here"
