    are you running DNS off of a regular router or are you using Windows Server and have it forwarding outside requests?  From the IP address you have given it sounds like you are using a normal Linksys router.

    Try switching the DNS forwarder to and see if it changes.

    but if you get prober nslookup response the problem is not in DNS.

    Did you try to clean temp on computer?? CCleaner for example.
    Try tu restart router and network devices.

    Try to restart Servers and after computers.
