Hi List, IACC to ICC switching is not the problem; it's switching back to IACC and re-synchronizing the databases. IACC 2.0 has a d:/opt/fox/IACC/CoExistence directory with a text file called IACC-CP. This file lists all of the CPs to be configured with IACC along with their host XP name and IP address. It IS possible (although probably not recommended) to switch CPs back and forth from IACC to ICC by adding or deleting the line referencing the target CP, saving the file, and waiting a few seconds for the Destinations.dat file to automatically update. Once the Destinations.dat file updates (sans the target CP), you can call up ICC for that CP. I've found this "feature" useful during early stages of the IACC "learning curve" to see what is really going on with the configuration...
