When trying to start Sage 100 ERP Advanced 2014 from a workstation I receive the message, ""Unable to connect to server: ""SEVERNAME"". The server cannot be found."". I can access the server just fine. The installation was done across the network, with no errors. I can Ping the server. I have uninstalled and reinstalled many times. Tried it with IP address instead of server name, tried on other workstations. The service is running on the server and we can run Sage on the server without a problem. The problem appears to be that the port is blocked, but I can't figure out how. We've turned off any firewalls or anti-virus. I'm using port 9999,(have tried others). Running portqry on the server for that port answers LISTENING, portqry run on the workstation to the server answers FILTERED. The entire 9000 range answers FILTERED. I'm logged in as the administrator. I don't know what else to try.
***Update***
I ran netstat and the PID for port 9999 was 1184. Task Manager shows the Sage service running with PID 1184. The program works on the server and netstat and portqry show port 9999 LISTENING, it's just when I try to access it from any other machine that I have a problem.
