    I am experiencing consistent and frequent network drop outs on the guest OS (Windows XP Pro). I am having a difficult time troubleshooting this.

    Has anyone else or is anyone else experienceing this issue?

    This is a new behavior, but I have made no changes recently to either the guest OS or OS X.

    Thanks in advance for assistance.

    I have most of the evening collecting data -
    I can ping out to several different sites from windows simultaneously and I get "Request Timed Out" on each ping at the same time.
    This happens every 50 to 53 pings
    I can also ping the same sites from OS X and not see this behavior.
    I can ping my default gateway and not see this behavior.


    I'd say this is a problem

    Try to switch to Shared Network (or to Bridged Ethernet) and check is the same situation is out there

    Firewall, Antivirus (on both sides)?

    This took me quite a bit of poking around to find this - I have a netgear router that just took a new firmware version. Apparently the update selected this option "DHCP Client Renew Mechanism Release / Renew when 'DNS lookup' failed", I found this purely by accident by reviewing the Router logs and found an event for "Failed DNS lookup", I then stumbled on this setting - I unselected the setting, rebooted the router and all is well.

    I have to say that it is very difficult to investigate issues across two platforms when one behaves differently than the other.

    Could update to Airport Extreme cause a similar issue?

    Interesting that you post this because I just did a firmware update to my Apple Airport Extreme router and I think that may have been when I started having problems. Not thinking that was the case, I've been installing/uninstalling Parallels & Vista, repairing permissions, etc. all to no avail. Each time one thing gets fixed and another thing pops up. I'm not completely tech illiterate but I'm not too savvy with the advanced commands so I'm wondering if there is any suggestion for how laypeople like myself can check my router file and know what to look for (and what to do once I find it). Any help would be greatly appreciated.

    Thanks.

    I have logging enabled on my router - I was looking throughthe logs looking for any clue I could get and saw the error - and it was happning frequent enough that it could have been my problem. Ironically I stumbled onto the setting and I put two and three together to get five. It helped that the error being thrown and the setting had enough information in them to match up.
