  We have a SQL server 2008 Cluster instance. Our SSIS package failed early morning. And the web site uses it shows:

  Cannot connect to the configuration database.

  Also I see some maintenance plan failed on the server. It said cannot connect to the instance.

  This cluster has two instances installed on it.

  In windows error log, I also see something like below:The SQLBrowser service was unable to process a client request.

  I see all the sql services is running, I restart SQL browser.

  Half an hour later, the site is running again. Not sure if it is the reason I restart SQL browser, or any other things happened.

  It is running now, but we would like to figure out why the connection is broken.

  Any ideas? Thanks
