I am currently in the process of updating an application that we use here for faxing and the new version requires windows 2008 R2 64Bit.
My domain is a windows 2003 AD running on function level 2000 Mixed.
My question is this: Can I install windows 2008 R2 64bit Server as normal and join it to the domain? It will not be a DC or run any roles.
We will be updating all the servers at some point to 2008 at which point I will raise function levels but this application only requires the 2008 os.
Thanks in advance for the help
