I got this error recently, and could find almost no useful posts about what caused it and how to solve it, so here's what I found. It's simple!
When the "domain guy" in our company setup the domain account that SQL Server Agent runs under up, he didn't check "password never expires", so the account's password had expired, causing all the Integration Services packages that connect to Windows Authentication connections to fail. I modified the account in Active Directory Users and Computers to never expire, reran the packages, and they succeeded.
So, to summarize, make sure the account you're using for SQL Server Agent is in a good state as your first level of troubleshooting!
