To accomplish using SSRS2008 report builder with CRM 4.0 I see there are 3 options and I'm not sure which works:
1. Install CRM on SQL05 and connect to a SQL05 Report Server then attempt to upload a 2008 RDL (pretty sure this won't work)
2. Install CRM on SQL05 and connect to a SQL08 Report Server then attempt to upload a 2008 RDL (not sure if this works)
3. Install CRM on SQL08 and connect to a SQL08 Report Server then attempt to upload a 2008 RDL (not sure if this works)
