Trying to ping (then VNC) to a remote computer that is using dynamic dns provided by DynDns.org (name.dnsalias.com). Ping is trying to connect to the OLD ip address rather than the current one. nslookup returns the current and correct ip address which tells me my local dns server is working. I only have the 1 dns server listed when I check ipconfig /all and that is my local dns server. running nslookup or ping on the server returns the correct ip address. ipconfig /displaydns does not list the address but I have tried ipconfig /flushdns anyway. I have tried adding the MaxCacheTtl setting to the registry and setting it to 1 second. I have also tried stopping the DNSCache/Client service. ping still tries the OLD ip address!!!!
