# Installing Software on Offline Computers

Using Apple Remote Desktop, you can install software on a computer that is not currently connected to the network (with a status of "Offline"). This is referred to as AutoInstall. The installation does not occur when initially ordered, but when the offline computer next becomes available. The installation itself is handled by a designated 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.

Remote Desktop first copies the installation package to the Task Server, and gives the Task Server the necessary instructions to install the package to all the selected computers, even if some of them are offline. The Task Server monitors the network for the next time the offline client comes online again. When the client comes online, it contacts the Task Server and notifies it of its network state and any setting changes (like a DHCP-assigned IP address change). The Task Server then begins the installation. If a client goes offline during AutoInstall, the installation fails and restarts from the beginning when the client comes back online.

To use AutoInstall, you need to do the following:

- Make sure each client can be accessed by the Task Server.
- Ensure network access to the Task Server from each client network segment.

  A network's topology and router configuration can keep the client computers in the administrator's list from being accessible to the designated Task Server. This can lead to installation commands that can never be completed.

- Make sure you have the network resources to perform the installation task for every client at any given time.

  Your network may be sensitive to sudden increases in network activity at unexpected intervals, as designated copy recipients rejoin the network at different times.

For information about setting up and using a Task Server, see Working with the Task Server.
