We've ARS 6.8 installed in our environment which is managing multiple domains. I want to force ARS administration service to prefer a 2008 or later version DirSync server when i select "Any available domain controller in a particular site" option & the chosen site has a mix of 2003, 2008 & 2008 R2 domain controllers.
This helps me in running certain scripts which utilise attributes suck has msDs-SiteName, which are unavailable if the admin service is connected to a 2003 domain controller instead of 2008 dc.
