I have ESS 3.0.669.0 on XP pro SP2 Everytime I browse a network drive event id 6004 [A driver packet received from the I/O subsystem was invalid. The data is the packet] gets logged . When I uninstall ESS the problem goes away. I noticed that is was a big issue with NOD32 and was finally resolved by ESET. Is anyone else having this problem and does anyone know if ESET is working on a fix for ESS? Thanks in advance.
