Problema para conectar al Integration Services con SQL Server 2005

Hola a todos, estoy intentando conectarme al Integration Services (las
antiguas DTS del SQL Server 2000) desde mi máquina usando el Management
Studio, me aparece una ventana de error que contiene una opción llamada
"show technical details" que al seleccionarla obtengo el siguiente error:

=>
