Google for "sep_sbs_bestpractices.pdf" for the Best practices installing on SNS2003 (There are some special considerations, especially if you are also running SEPM v11. Also google for sep_sbs_bestpractices_policyfiles_mr2.zip as these are predefined central exception policies that you can import to avoid any scanning issues. Based on these docs, this is supported, at least with MR2. I just rolled this out to a client
