Before you perform an in-place upgrade, you must determine which network drivers the instance is running. PV network drivers enable you to access your instance using Remote Desktop. Starting with Windows Server 2008 R2, instances use either AWS PV, Intel Network Adapter, or the Enhanced Networking drivers. Instances with Windows Server 2003 and Windows Server 2008 use Citrix PV drivers. For more information, see Paravirtual drivers for Windows instances.
Citrix PV drivers are used in Windows Server 2003 and 2008. There is a known issue during the upgrade process where Windows Setup removes portions of the Citrix PV drivers that enable you to connect to the instance by using Remote Desktop. To avoid this problem, the following procedure describes how to use the Upgrade Helper Service during your in-place upgrade.
