Unable to Connect to Local SQL Server with Windows Authentication using SSMS

I'm trying to login to my local SQL Server 2005 installed on Windows7 using SSMS using Windows authentication.

I tried using various server names like ., localhost, .\SQL, ANANTH-PC etc.

I get this error when I try . or localhost

And I get this error when I try .\SQL

.enter image description here

I had gone for default instance and Windows authentication when I installed SQL Server.

I've checked the service in the SQL Server Configuration manager and find that MSSQLSERVER is running.

How can I find the server name that I should enter to login to SQL Server? Any help ?

Error is loged as

2012-01-26 15:07:16.02 Logon       Login failed for user 'Ananth-PC\Ananth'. [CLIENT: <local machine>]
2012-01-26 15:08:51.06 Logon       Error: 18456, Severity: 14, State: 11.
