Build Networking
Virtual Desktop VLAN A separate Network VLAN for the virtual desktops and XenApp serverswill be created.
Create a DHCP scope Create a DHCP scope for the XenApp and VDI subnetsA redundant DHCP scope should be available for the subnet.
Verify DNS Redundancy XenDesktop and XenApp environments require DNS for inter-component communication. Therefore, it is vital to configure a minimum
of two DNS servers for each zone on every server and virtual desktopfor reasons of redundancy.
Verify DNS DynamicUpdates are enabled
XenDesktop requires a fully functioning DNS solution for the
XenDesktop Controllers as well as the Virtual Desktops. As Virtual
Desktops typically obtain IP addresses by means of dynamic DHCP the
ability to dynamic update DNS A-Records is required.
