Hi, I have installed SQL Server 2

Hi, I have installed SQL Server 2005 on a Vista Business. I am able to connect to SQL Server instance on Vista machine from Management Studio on other machine (Running on Xp). But I am not able to connect to Analysis Services default instance on Vista Business machine from Management Studio on other machine (Running on Xp). I did all settings with Vista firewall exceptions, SQL Surface area configuration, Security, everything. Please tell me do I need to modify something else on 'Vista Business'. Thank you.
