We want to get rid of our SBS 2003 server and use the new Server 2012 R2 in it's place. I joined the domain and installed A/D on the new server but it would not promote to DC. It claimed it couldn't find the DC even though it was logged on to the SBS server.
There are only a few users so I created a new domain on tyhe new Server & A/D configures fine. I have been able to join a XP PC but Win7 PCs don't see the domain. The SBS server is also DNS.
Anyway the new server idea requires recreating desktops for the 5 PCs so that's not a best case scenario.
What do I need to do on the SBS 2003 server to make it work with the Server 2012 R2? I have a DVD with the new server but it probably won't work on the old SBS server,
