Symptom
A user in Trados Studio is trying to connect to the SDL Trados GroupShare projects server but gets an error message similar to the above.
Probable cause
The following are all true:
  • The Trados GroupShare projects Application Server has a firewall (or is behind a firewall).
  • At installation time, the option 'Integrated security' (or, equivalently, 'Windows authentication') was chosen.
  • The firewall was not given a rule to allow incoming TCP traffic on the port specified for the Application Service.
Solution
Modify the firewall on the Trados GroupShare Application Server to allow the TCP port to accept connections on the appropriate port.
