How do I set up an alternate network configuration for field synchronization in CCH ProSystem fx® Engagement or Workpaper Manager when a DHCP server is not available?
The Alternate Configuration tab provides an option for setting up an Static IP Address. This is used when a DHCP server is not available. The Static IP Address needs to be a Private or Internal IP Address. The addresses set aside for this purpose are 10.0.0.0 – 10.255.255.255, 172.16.0.0 – 172.31.255.255, or 192.168.0.0 – 192.168.255.255. Using a Static IP Address and a Hosts file with the machine names and IP addresses on each user machine will provide an option to alleviate the connection issues.
