Just installed MS SQL Server 2005.  During setup, I selected use Windows Authenication mode to connect to the database engine.  After launching SQL, I can't connect because it says I'm not authorized to connect.  Do I have to do a re-install?

Go to MS SQL configuration manager and check the SQL Server engine it running or not, if it’s running  then try login using “.\(instance name)” which is given in the screen shot.  Mssql Connection Error

May be the windows user doesnt have a local admin rights.if your'e in a domain then check the domain user permissions.
if neither doesnt work  reinstall with mixed mode authentication and will be able to connect with a valid login.

Thank you responding.  Using the *.\(instance) did not work.  Said something about problem connecting to a remote server.  I will do a re-install and make sure I select the mixed mode authentication option.  Will let you know how it turned out.  Thanks again.

Make sure that  SQL Server engine is up and running. if its not running make it to run by changing the properties. once it is started use . as username and try to run. it will work

Had to do a re-install and set the proper properties during setup.  After installing, used SA account to make myself a SA under server role and everything worked fine.  Thanks
