Hello,
you can configure WPM to use domain accounts. Run "c:\Program Files (x86)\SolarWinds\Orion\SEUM\Player\SolarWinds.SEUM.AgentDomainConfigurationTool.exe" and it allows you to define domain accounts for player. You will need 2 (on main server) or 7 (on separate player) unique accounts. You can use same accounts on multiple players but single player allows to use each account just once.
