This application requires resolution of equipment names, whether by host files or domain name system (DNS). The Application Server cannot respond to Java clients based on their IP addresses alone. Clients may be on a different network and therefore would be unable to connect.
If your network does not have DNS, you can also assign hostnames in %windir%\system32\drivers\etc\hosts on Windows. You must assign a hostname in addition to an IP address in that file. Here are some example hosts file contents (including two commented lines where you would have to remove the # sign to make them effective):
# 126.96.36.199 rhino.acme.com # source server
# 188.8.131.52 x.acme.com # x client host
This software does not support installation to anything but the local file system. Avoid installing to shared drives.
