I have recently deployed 7.1 to all machines using EPO 2.5.1. Many of the machines are working fine but some are not updating their DAT files. The machines that are not working seem to be the ones on the shop floor which do not have an outside connection to the Internet. I have a repository set up internally which has worked perfectly with VS 4.5.1. The machines not updating are connecting successfully to the EPO server and updating the properties on the correct schedule. Just not updating the DATS. Any one see this problem and any suggestions?
