I have one server with outside access to McAfee which obtains DAT updates. Can that server be set up to provide clients with access to the updated DAT files via an HTTP service instead of UNC? I did not see anything in the manuals describing this scenario.
Each VSE client has a Sitelist which tells it what servers to try and connect with for updates, and what protocol to use (Http or FTP or UNC or local).
So yes, it can be done.
I suggest reviewing documentation and/or calling Support for assistance.
