Hi - I'm newbie to Eset but not firewalls in general, and I think I may be regretting my purchase........ Has anyone else had problems with Smart Security 4 and a Sonos music system? Since installing Eset my sonos controller can't access the network drives it needs to play music. If I uninstall Eset all is OK. I have tried all the usual checks I can find - my home network areas are all trusted zones, (my printer etc all work). If I uninstall Eset & reinstall it, the sonos works until I next turn off my pc, then on restarting Eset kills the network connection somehow. Has anyone got any clues or similar faults Also the Sonos desktop controller doesnt work at all with Eset running, but I can get around that if i can get my hand controller to work. thanks Oh - I'm on XP sp3 with no other problems!
