Enable script file synchronization for Windows enhanced security Windows Internet Explorer enhanced security blocks downloaded files that it determines are potentially dangerous. Enhanced security in Windows browsers, such as Internet Explorer, blocks downloaded files that it determines are potentially dangerous. This would block files downloaded for use by the MID Server. You would need to unblock each file manually through the browser. To get around this issue, use file synchronization. File synchronization requires you to proactively take script files from your instance and save them on the MID Server. The files on the instance and the MID server stay synchronized, but there is no longer any need for the MID Server to download the whole file. File synchronization also protects any updates you make in those script files from being overwritten during the upgrade of an instance. Script files synchronized with the MID Server are stored on the instance in the MID Server Script File [ecc_agent_script_file] table, which you can access in the MID Server > Script Files module. When the MID Server first connects to the instance, the instance creates a directory called \scripts in the MID Server root. The instance then creates a parent directory in the path \scripts\<parent name> using definitions from the ecc_agent_script_file table. Finally, the instance creates the script files themselves inside the parent directory using the records from the ecc_agent_script_file table. The record for the parent directory looks like this: The instance creates each script file in the parent directory on the MID Server using the record Name from the ecc_agent_script_file table as the file name and the Script field payload as the file contents. A script file record looks like this: The synchronization of the script file continues to work as if the script was manually added to the form. See Attach a script file to a MID Server for instructions on how to attach a script file. Note: The MID Server Script File [ecc_agent_script_file] table is domain separated. You can create versions of these policies that only a MID Server from the same domain can use. For instructions, see Set up domain separation for MID servers.
