Service Unavailable? this is error is coming when I the typed URL in the url bar for sharepoint site?can any one help me out...

1. Check the IIS application pool serving the IIS web site (SharePoint web application). Is it started? 2. Check the identity of the IIS application pool. Is it valid? Is the password what it should be? 3. Check the server event log for W3SVC events.Cheers! Sridhar.. If you find this post helpful, please click the 'Vote as Helpful' link.
