Reach Data Analysis through 2 trusted domains - Robert

Hello;
I have two trusted Windows 2003 domains : DomA and DomB
Project Server 2007 and SQL Server 2000 and Analysis Services are installed
on DomA.
From DomB I can reach PWA (Project Server) on DomA as well as Central
Administation of WSS.
But when I try to reach a Data Analysis view (OLAP Cube), I get the error :
computer denied it explicitly."
Any idea to reach Data Analysis through 2 trusted domains?
Thanks for yor help.
