We currently have 2 NPS servers on their own Windows 2008 R2 VM's in a cluster that are not Domain Controllers.
Moving forward we want to get rid of the current NPS servers because for Windows clustering to work we had to use Raw Device Mappings (RDM's) and its caused nothing but issues.
I'm planning to build brand new 2012 servers with NPS, but should I promote these to DC's once we migrate our existing PDC and other DC's to 2012? Or is it best to have the NPS role on their own servers without being domain replicas?
We have about 500 wireless access points talking to the existing NPS servers with roughly 7500 users in total.
