Re: Loss of Connectivity on Only One PC on a LANI had posted about this towards the end of last month. MVP Chuck had been trying to help me through this. I'm updating the situation with some new info, and. reposting it since that thread goes back several weeks. My apologies if this isn't the appropriate way to do this. The original thread may be found at: http://groups.google.com/group/microsoft.public.windowsxp.network_web/browse_thread/thread/6529be7c79cd41d2/# To recap: I have a LAN setup with only two PC's. The connection is via a Linksys BEFSR41 Router. My own PC occasionally loses connectivity~every one to three days. This is noted by a yellow exclamation mark at the LAN icon in the System Tray, telling me that my connection has limited or no connectivity. It is generally preceded by some warning readings in the Event Viewer about "Failure to renew address" on the network from the DHCP server. The other PC, however-a Laptop-NEVER loses connectivity. For a week, the connectivity problems on my end had stopped. When they resumed last week, I no longer was able to regain the connection by simply disconnecting my PC from the router-as was the case late last month.. I had to shut the router down first, by unplugging and replugging it.. After reading Chuck's blog on properly setting up a Network such as the one we had intended:. http://nitecruzr.blogspot.com/2005/05/using-network-setup-wizard-in-windows.html I asked my roommate if she recalls how she had set up the Network Setup Wizard in the first place. She seemed to recall checking in the option: · This computer connects directly to the Internet. The other computers on my network connect to the Internet through this computer. Rather than the correct option: This computer connects to the Internet through another computer on my network or through a residential gateway. Since we are using the Linksys Router for both our PC's the second option would have been the correct one. In addition to the connectivity shutdowns described earlier, I also notice that I cannot find locate her PC in My Network Places, nor can we ping one another. This in itself isn't a problem, since we don't share printers or files. I mention it only insofar as it might be symptomatic of the underlying problem. Question: 1) Can she or I simply rerun the Network Setup Wizard, and this time check in the correct box? Will this simply override any configuration errors she may have made in the original network setup? Or is it necessary to change some settings and/or uninstall /reinstall some hardware or software first? 2) Since we both access the internet separately via the Linksys router, should I run the Network Setup Wizard as well? Do both users need to run the Network Setup Wizard? Thanks again for bearing with me on this: -Eli Windows XP Professional Edition SP2 Zone Alarm Security Suite 6.1.744.001

I wish all folks asking for help here could be so diligent. Rerunning the NSW will not hurt. You could run it on both computers, but to diagnose the problem running it on one computer at a time would make more sense. Then examine the symptoms again. Use the output from "browstat status" and "ipconfig /all", from each computer, to diagnose the problem. Read this article, and linked articles, and follow instructions precisely (download browstat!): <http://nitecruzr.blogspot.com/2005/05/troubleshooting-network-neighborhood.html#AskingForHelp> http://nitecruzr.blogspot.com/2005/05/troubleshooting-network-neighborhood.html#AskingForHelp Now if you don't share files, then you probably haven't setup any shares. That in itself will prevent the computers from appearing in My Network Places. The inability to ping one from the other is a bit troubling though. Do you get dropped packets, or "unknown host", when you try to ping? -- Cheers, Chuck, MS-MVP [Windows - Networking] http://nitecruzr.blogspot.com/ Paranoia is not a problem, when it's a normal response from experience.

" The inability to ping one from the other is a bit troubling though. Do you get dropped packets, or "unknown host", when you try to ping?" ============================================== Hi again, Chuck. I'll look into those articles u mentioned. I just tried to ping again. I used her internal , network IP. The results at Command Prompt were: "Request timed out" 4 packets sent. 4 packets lost. Her PC is in hibernation now, but when I tried this while it was on and running , I'm, almost sure I had gotten the same results. OTOH, when I ping myself, no packets are lost. At ipconfig/all, the readings are as expected. The DHCP server and Default Gateway have the same address. DHCP and Autoconfiguration are both Enabled. the Network Adapter being used in this LAN is correctly named. As mentioned in an earlier post, the Network Dx tool in Help and Support shows everything ok while the connection is functional.

As mentioned in an earlier post, the Network Dx tool in Help and Support shows everything ok while the connection is functional. We need to isolate the problem. So far, you've referred to 2 symptoms: 1) Your computer intermittent loss of connectivity. 2) Your inability to ping the other computer. So start by posting output from "browstat status" and "ipconfig /all" from each computer, here. There's lots more work we will do, but this is a start. <http://nitecruzr.blogspot.com/2005/05/troubleshooting-network-neighborhood.html#AskingForHelp> http://nitecruzr.blogspot.com/2005/05/troubleshooting-network-neighborhood.html#AskingForHel -- Cheers, Chuck, MS-MVP [Windows - Networking] http://nitecruzr.blogspot.com/ Paranoia is not a problem, when it's a normal response from experience.
