SSIS Runs Locally, But Not On Server - Help!

My team is using SqlServer 2005 SSIS to develop package for Consolidated Views. This works fine on my machine in Visual Studio when they run it as a script from command prompt from their desktop. However, when they move this package to ETL box, the package runs fine Visual Studio environment but fails when run from the script with the errors:

Can someone help us understand the problem? We are new to SSIS. We also want to know exactly what needs to be on the Server that will be running our SSIS ETL programs (that is, what components of SSIS -- SQL Server 2K5 is already loaded).

We are using SQL 2005 on Dell Servers running Win 2003, with the latest service packs. Microsoft SQL Server Integration Services Designer Version 9.00.2047.00
