Desktop automatically contacts the Task Server for the report data and displays it The report data resides on the Task Server and should be backed up from the Task Server not from the administrator computer Using the Task Server for Autolnstall Once the Task Server is set up in Remote Desktop on the administrator computer it s easy to use the Task Server for Autolnstall If you choose to use the Task Server the installation uses unicast network traffic in client groups of 10 instead of the multicast traffic used when the Remote Desktop application performs the installation If a particular client is offline during the installation the package is held for it When it comes online it contacts the Task Server and the Task Server begins the installation To use Autolnstall When choosing installation options from the Install task window select Run this task from the Task Server instead of from the application Remote Desktop copies the installation package to the Task Server first and gives the Task Server the necessary instructions to install the package to all the selected computers even if some of them are offline When an offline client comes back online the installation proceeds Chapter 3 Task Server Scenario

11. sing additional Task Server computers Increasing the number of Task Server computers and dividing the network may lead to better performance and better network citizenship However since there is no way to aggregate report data across Task Servers and display it on one administrator computer you would need multiple administrators to balance your network load If you use a single database for a large number of clients you may need to stagger the generation of report caches For example if you normally run a report every week then set 1 7th of your clients to rebuild caches on day one another 1 7th on the next day and so on You could also stagger the cache rebuild over the course of the day Have enough disk space for the report data cache on the Task Server The file system report data that is uploaded to the report database for a client with 10 GB of files on the hard disk can easily reach 5 MB With hundreds or thousands of clients this can add up quickly Data for other reports System Overview Application Usage and User History are only 8 KB to 12 KB each and have little impact Uploading user accounting data and application usage data further increases the size of the data cache for each client Since you may not want to store all the possible information for a given client computer you should customize which type of data is collected and plan accordingly Planning to Deploy a Task Server for Package Installation Using a Ta
