NetTalk Server being shut down - Virutal Server

[CaseyR]

Hi, all

Two clients report that our NetTalk application closes when a user tries to connect with their browser.  I observed the problem in a remote session. In both cases they were using a virtual Server 2016 or 2012.  I haven't able to replicate the problem here so I think it is a security protocol of some sort but can't find an obvious reference.  They have created inbound exceptions in the firewall but even localhost calls trigger the shutdown. There is nothing in the event log after "Listening on port ..."  These are new installations so the clients are just trying to get it to connect on an insecure port to start.

If anyone has a suggestion about where to look, it would be greatly appreciated.   Thanks.

If you have GPF reporter, add that to the app and see whether it's actually crashing rather than being forced to close by the OS.
