Install CRM 4.0 in a Windows 2008 Cluster

Hello,

i'm trying to install a CRM 4.0(WebAS 620) instance in a W2088 Cluster (previous to an upgrade to a CRM 7.01)

Does anyone have experience with this kind of installation?.

I have installed a standard SAP system but when i try the conversion to MSCS (Configuring MSCS Node A in sapinst) i have a lot of problems.

Thanks, Angel
