We are in the process of de-commissioning a Windows 2003 Server that is one of our domain controllers. Due to its' presence, the Domain Function Level for our network is set to Windows Server 2003. When I replace this DC with a new one, the minimum DFL support will be Windows Server 2008. I am trying to find out if our NAV version (NAV 4.03 SP3) will work on a Win2008 DFL. I have found some general statements regarding NAV 4.03 and DFLs, but nothing definitive. Any insights would be appreciated.
