Just in case you get bored over the holiday weekend (@DougHiggs ) v2017 PU 4 ADV on Windows Server 2016 - Having a ""server disconnected"" issue on a new install. Found the attached KB and feel I have ruled out the possible culprits presented. I guess only time will tell. Has anyone else run into this issue and what have been the solutions? Are there possible other culprits? Client also reports that Crystal response time is slow. Have tried the CS ODBC both Service on and off. I have also run into the server disconnected issue on my office Server 2012 R2 running V2018 ADV. For some reason, on this install, it disconnects ONLY when I print v2018 PR checks. If I print PR checks in STD mode, it does not disconnect. Very strange. TIA for the thoughts.
