  • What exactly have you tried yesterday?

    Try turning off the Sales-74 computer, or unplug the network wire from the wall. Then ping the 192.168.x.xx  address that is in the error message. Does it respond? If so, run nslookup 192.168.x.xx to see what machine has it (relies on a reverse zone to find this info). If you don't have a reverse zone, physically look in the DHCP lease database to see what machine has that IP.

    If no response pinging it, then you can delete the lease in the database, and plug the machine back into the network, re-run the ipconfig /release and ipconfig /renew.

    Let us know if this works.

  • I'll go with Ace on this one. Also check your IP address pool (DHCP Scope) and check if you have enough free IP addresses. decrease Scope lease time if applicable.

  • I have been struggling with this problem for MONTHS. My PC would lose connectivity every 3-4 hours and I would have to re-power my router to get connectivity back. I tried everything I could find online - new drivers, disabling sleep on the PC, everything in this thread, and much, much more. I finally came across Jack's reply on this link:http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/i-work-technical-support-for-a-broadband-isp-have/469a81b8-7ab6-4993-a479-b38c67a51756, and it worked.

    I really wish that Microsoft would be able to incorporate this into the network troubleshooting and/or create a Mr. fix-it for this but in the meantime if you are having trouble with your internet dropping, try this.

    I hope Jack's solution will help others too.
