First of all, on Windows server you should install ESET File Security. Please uninstall EEA and install EFSW 7.2. Secondly, v5.0 is a legacy version which is in limited support and will have reached EOL by the end of this year.

Please update ESET products to the latest version. If you have offline computers, use the ESET Mirror tool to create a mirror (https://help.eset.com/esmc_install/70/en-US/mirror_tool_windows.html). If the machines have access to a computer connected to the Internet, install an HTTP proxy server (it's a part of the ESMC all-in-one installer) and configure clients to update through it.
