Hope this helps:
From their main page: McAfee ePO System Requirements
Database (32-bit and 64-bit):
SQL Server 2008 with SP1/SP2/R2 Standard, Enterprise, Workgroup, Express
SQL Server 2005 with SP3 Standard, Enterprise, Workgroup, Express
"Service Packs - within 30 business days of the official Microsoft GA (general availability) date"
Thanks for the info. I saw the requirements specifying that R2 was supported, but didn't seen any indication about SP1 for R2. But based on that KB article, it looks like that the R2 SP1 would be supported 30 days after the GA release. Many Thanks.
