hi...
i m building my first web site "wrox united"..
When coming to the chapter manipulating security tab for user accounts and defining roles....in web site administration tool...i am facing an error specifying

"An error occurred during the execution of the SQL file 'InstallMembership.sql'. The SQL error number is -2 and the SqlException message is: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."

but on downloading the code for the website i find that this security tab works...

please clarify....
