I'm not sure what you mean about my DataCare being installed on a local machine. DataCare is installed with both the program and the data on the server, the same as every other Adagio module. It was working fine until we installed the IC 8.1C Upgrade. We have not resolved this issue. The error occurs from all XP Workstations, but not if you run the program locally from the SBS 2003 server. Please let me know if you figure out a fix.
