how to run a simple sql query - dumb question

I am new to SQL Server 2008 (the newest version we have).  We have been running SQL 2000 for a number of years and so my limited experience is with that version.  What my question is, is I am trying to run a script and it appears that SQL 2008 does not have SQL Query Analyzer like SQL 2000 had.  Can someone tell me what tool is available in SQL 2008 that can be used to perform similar task that previously were done using SQL Query Analyzer?  I am trying to run a script to verify some logins by selecting "New Query" from withing SQL Mgmt Studio but the script never ends and doesn't return any results.  I don't get an error either.

This is the script.

SELECT name, type_desc
FROM sys.server_principals
