Can ENS be installed on the UnitySync server?

Errors related to Trellix Endpoint Security (ENS)

ENS may be installed on the UnitySync server.

Below are examples of the error that may occur when ENS is installed on the Unitysync server. This error occurs when trying to view the Unitysync UI (via IIS or direwb)

Error 500, Internal server CGI program sent malformed or too big
OR
(500) Internal Server Error Error 500: Internal Server Error CGI program sent malformed or too big (>16384 bytes) HTTP headers: [] URL: config.cgi/key?_=1699484758

There are two workarounds (depending if you use IIS or Dirweb).

1. When Dirweb OR IIS is in use, within ENS settings, you may add an exclusion in ENS for the Unitysync install directory (i.e. c:\UnitySync-v4.7)

2. There is an alternate workaround that applies to IIS only. In IIS settings, Disable CGI Impersonate User. The default is set to enabled (TRUE). Change this to FALSE. The error 500 should no longer occur.

Troubleshooting

To isolate ENS as the issue, temporarily uninstall ENS.
If the error goes away when ENS is uninstalled, then you’ve confirmed ENS is the conflict. You should use one of the above two workarounds.
