Did a system restore this morning. All worked fine, coms with VL 8.6.3 & Z VIEW. Finished some charts on ZVIEW. Worked fine for ± 1 hour....all coms lost again, except ping still works!! Had enough of Win 7's PMS-BS, formatting and reloading XP Prof

Am having some major comunication problems with Windows 7 Pro 64 bit over TCP/IP and Vision 130, Visilogic 8.6.3....Did all the programming and testing form my laptop running XP pro, no problem whatsover. Installer VL 8.6.3 on Win 7 PC, and copied program accros. Had coms via TCP/IP but all of a sudden lost it. Can still ping the PLC, vislogic reports a coms failure error. Also uses Zview scada, lost coms at the same time. Uninstalled all antivirus software (Kapersky 2011 IS) Did system restore to before I coppied program. Had coms for ± 5 minutes....all coms gone again...except ping. I suspect something in Windows 7 is blocking it. Have set UAC to lowest level, also gone to the program folder of visilogic app and right click-. run as administrator..not luck. Saw that a critical windows was installed at more or less the time I lost coms. Ran system restore again...still no luck.... Any ideas?
