Report in SSRS using cube in SQL 2000

I want to create reports in SSRS that use cube in SQL 2000, I don't know which type of connection that i have to use,

I tested it with Microsoft SQL Analysis Services, means I connect to my cube with this type , everything is ok in developpement (create MDX query , make reports...), but in production It gives me this error message (cannot connect to the datasource),

so I don't know how to solve this problem,

Thanks in advance for your help...,

Regards

Posting the full error message would help.

Posting it in the Reporting Services forum would help even more.
