Cause

The IP and the name of the Application Server are not mapped in your hosts file.

Solution

Add the IP of the Application Server and the name of the Application Server to your hosts file (\Windows\System32\drivers\etc).
Your system admin can help.

Mapping the hosts file

The 'hosts' file has to be adjusted on the machine on which the Performer Suite runs (Path: "C:\Windows\System32\drivers\etc\hosts")

Map the IP to the hostname:
<IP> <hostname>
