I have an RODC in a remote site. It is currently running Server 2008 32-bit. Company policy is for all servers to be 64-bit. Is it possible to demote the RODC, remove it from the domain, install Windows 2008 64-bit and promote it to an RODC using the same hostname, or does it have to have a different hostname?
On a side note, we are in the process of migrating our workstations to Windows 7 from Vista. We have 2008 R2 licenses. Is it worth installing 2008 R2 on the RODC or stick with 2008?
