Home Networking Problem.

Question

My Computer is a Desktop Inspiron 530, Microsoft XP Professional Version 2002, Service Pack 3, Intel Core, Quad CPU Q6600@2.40GHz, 3 GB RAM.
Here is the problem, I used to connect to my home network through a Broadcom connection on my computer, and all was fine, on Wednesday 09/17/08, all the virus bells and whistles for McAfee virus-scan and Malwarebytes Anti-Malware went off and, somehow (and I can’t figure out how) I contracted a virus that seized my computer (task manager, and several other critical components were gone), the virus (Application Data\Microsoft\Internet Explorer\Quick Launch\Smart Antivirus-2009.lnk (Rogue.SmartAntivirus) -> Quarantined and deleted successfully.) kept telling me I needed to purchase the software. Anyway it was all deleted and the sytem was restored successfully, I thought! However, I still have a problem and I can’t for the life of me solve it. We have two computers in the house, and the second one runs Windows Vista and was totally unaffected. My home network is ATT highspeed DSL and is connected through a Motorola 2210 modem, a Netgear 5 port 10/100 MBPS Fast Ethernet Switch model FS105 (this is a new router purchased 09/24/08). I can connect directly to the modem and the internet-DSL works just fine, but when I connect to the router port I get a limited or no connectivity message and the Vista computer works just fine, if I connect my computer to the router port first it works great, and the Vista computer can’t connect. I am totally confused as to what happened. My connection shows that I am using Intel 82562V-2 10/100 Network Connection. Any help anyone can offer would most certainly be appreciated.

Thanks

Check the configuration of the two computers.  It sounds to me like they are sharing a setting they shouldn't (e.g., both have the same computer name or IP address).  Posting the results of ipconfig /all might help people identify the problem for you as well.

Here is the configuration for both machines XP COMPUTER is a INSPIRON 530 I can tell they use the same IP address, Subnet Gateway, DHS and DHCP servers. The Problem is I am not smart enough to know how to configure all the IP address DNS DHCP and subnets different, I have tried various combinations of numbers but never seem to get the right combinations, the Computer names are different. Again any help - will seriously be appreciated!!!! Thanks Larry R for the help:smileyhappy:.

Since there is apparently no solution to the problem posed here, I have retired the Dells and purchased two of another brand, unfortunately this ends a long relationship with with Dell.

Larry R · Answer

In your previous post you specifically state the two computers are using the same IP address. No two devices on a single network can share the same address. If they do then at best one is dropped from the network (I've never seen a pattern as to it dropping the first or second computer to connect with the address, it seems random) or at worst both computers will fail to connect due to the IP address conflict.

The fix to to ensure each computer on the local network has its own unique IP address.

Thanks for the help Larry, mute point now, I didn't know how to fix as I stated (see quotes below)once I posted the IPconfig. I donated them both to one of the schools here since one was less than a year old and the other one was 2 yrs old, I do appreciat your help, and your response Thanks again.

I completely understand. I'm also (personally) happy to hear they found a good home, even if you were done with 'em. :D

While it doesn't really matter now, the easiest solution is to set the router to the default settings (which should enable it as the DHCP server, to hand out addresses) and set the computers to "Obtain IP address automatically" in the Network Properties window for the cards. This is the default setting for Windows, so at worst you could "delete" the network card from Device Manager and have Windows reload the drivers (happens automatically when you restart the computer).
