The basic requirement for remote installation is a correctly configured TCP/IP network which provides reliable client server communication. Installing a client solution using ERA imposes stricter conditions on the client workstation than a direct installation. The following conditions should be met for remote installation:

· Microsoft network client enabled
· File and printer sharing service enabled
· The file sharing ports (445, 135 – 139) are accessible
· TCP/IP protocol
· Administrative share ADMIN$ enabled
· Client can respond to PING requests
· Connectivity of ERAS and ERAC (ports 2221−2224 are accessible)
· Administrator username and password exists for client workstations (username cannot be left blank)
· Simple file sharing disabled
· Server service enabled
· Remote Registry service enabled


NOTE: Recent versions of Microsoft Windows (Windows Vista, Windows Server 2008 and Windows 7) enforce security policies limiting local user account permissions so that the user may not be able to execute specific network operations. If your ERA service is running on a local user account, push installation issues may occur in certain specific network configurations (e.g. when installing remotely from domain to workgroup). When using Windows Vista, Windows Server 2008 or Windows 7, we recommend running the ERA service on accounts with sufficient networking rights. To specify the user account on which you want to run ERA, navigate to StartControl PanelAdministrative ToolsServices. Select ESET Remote Administrator Server service from the list and click the Log On tab. ESET Remote Administrator 4 embeds this setting in the Advanced installation scenario so you must select AdvancedFully customized installation during the installation. If you are using Push Installation on Windows Vista, Windows Server 2008, or Windows 7 target  workstations, make sure that your ERA Server as well as the target workstations are in a domain.


We highly recommend that you check all requirements before installation, especially if there are multiple workstations in the network (on the Remote Install tab select the Computers tab, right-click the relevant client(s) and select Diagnostics of Push Installation from the context menu).
