I have a vista pc, on SBS domain, static ip/dns. disabled the IPV6, only IPv4 running. Intermittently the network connection drops and the ASDM syslog shows internet connection denied...flags PSH ACK interface inside and then also deny inbound UDP.....to DNS query. Idisabled the autotuning/scaling on the vista, but I dont know what to do on the router side. I am really rusty on the ASA and need some direction please!! thanks!
