Just an FYI if you are going to upgrade to SAM 6.1 this is in the SAM admin guide now:
http://www.solarwinds.com/documentation/apm/docs/SAMAdminGuide.pdf
On Page 102 in the SQL section it states:
SQL Server 2005 SP1 Express, Standard, or Enterprise
(Important: Not supported in SAM 6.1+.)
Also on page 104 there is also this caveat:
Important: If you are running Windows Server 2008, you must upgrade to
Windows Server 2008 R2 because SolarWinds SAM does not support Windows
Server 2008 due to known WMI issues
PS really likeing NPM 10.7 and SAM 6.1! Definitely worth the upgrade
