I recently created a Windows 2012 R2 Hyper-V host and then migrated several machines (using VMM 2012) from a Windows 2008 R2 Hyper-V host.
The Windows 7 machines are working fine, integration-wise, but some of the Windows XP SP3 machines cannot get integration services working. A couple of the Windows XP machines integration services are working fine. I don't see anything obvious which would be causing the discrepancy.
On the machines that it is not working, I have tried:
uninstalling the services, rebooting, and reinstalling the windows 2012 r2 vmguest.iso image files
uninstalling the services, rebooting, and reinstalling the windows 2008 r2 vmguest.iso image files
Suggestions?
