Has anyone had any sucess running Internetware 4.2 on a Hyper-V session under Windows 2008 server with Windows XP clients. I have a custom DOS based accounting system that needs to be preserved. I thought of this after reading for the MCITP exam, feeling I could kill two birds with one stone. Using newer hardware with virtualization, Active Directory, and RAID 10. I have been lucky to get 10 years out the DOS server I built, I cant expect it to last forever.
