modified. These modifications allow the server to become part of the XenApp farm during server delivery, as
explained in the XenApp Integration step.
Startup Phase: The server is no longer using its localized operating system present on its local storage. Instead, the
server must receive its role across the network. This process takes the following steps during startup:
A physical/virtual server starts and requests an IP address from the DHCP server. The DHCP response
includes two additional configuration options telling the server what the boot program is called and what server
can deliver the boot program.
The server makes a TFTP request for the boot program from the specified server
The Provisioning Server sends the boot program to the requesting server
The server executes the boot program
The boot program determines, based on the Provisioning Server configuration, which image the server should
receive based on the server‟s MAC address
The image is streamed to the server so the server can launch he operating system. Additional data is
continually streamed to the server throughout the duration of the session.
During startup, the server uses the installed Provisioning Server drivers to change the computer name to the
specified value within the Provisioning Server Console
XenApp Integration: XenApp environments store member server information within the data store. This information is
created when a new server is added. The information is modified based on changes made within the XenApp
management console. Because a group of XenApp servers share the same role, they originate from the same base
Provisioning Server image. Each server must have its presence established within the data store. This is accomplished
by the following:
When the server starts and its computer name has been changed based on the previous processes, a XenApp
integration utility is automatically executed
The utility adds/syncs the server with the XenApp data store by restarting the XenApp services
The XenApp server receives its instructions for published applications and starts accepting connections
