Whereas device manager does show our driver as Napatech, 5/13/2011, Ver 4.22.2.0 we have not had any issues as of today though it is definetly something to know and keep an eye on. It is more the issue that packetcapture.exe restarts and then, according to the enforce console, goes looking for the Endace DAG drivers. This then translates in the eventvwr to the packet capture falters and then NtxDrv errors that seem to correspond to the box trying to load the Endace drivers which were uninstalled. Not sure what I'm missing. Is there a path somewhere that needs to be changed? And what is the certified 4.22 driver for DLP 11.6.2?
