Urgent Win XP network limited connectivity error

Hi,
My pc recently rebooted from a windows update. And now my network cannot be accessed.

There are 3 other PC's on the network.

I have tried to release ip and renew it does not work.
I have tried to rollback the driver, it does not work.
I have tried to system restore to a week before and it still does not work.

Tried to install an updated driver for the network card. Still nothing.

There is a icon with a caution triangle saying limited or no connectivity, but it does not connect to any mapped network drives or to the internet

Hi,
Try to set up manually an ip address. If you still a got limited connection, you should check the cable, switch, router... in this order.

Good luck.

1. click on start -> run
2. type cmd
3. in the window that has opened type ipconfig /all
4. you should see an ip address - if it is 169.x.x.x then you are not able to communicate with your DHCP server if it is anything else, check the properties for the NIC and make sure an ip address has not been assigned manually
5. Check your DHCP server - do you have enough leases available?
6. take the cable from one of the working machines and use it on the machine with issues - does this solve the connectivity - if so get a new cable.
7. if not then you are narrowed down to the NIC and the Port you are plugging into - try moving the computer to another port and try again try another NIC in the computer

wrote above and now read your recent post - are you logged in as an administrator of the machine?

It means that you have a limited user account on that system. Try to restart the router. That may help.

DONE the above still no joy.

5. Check your DHCP server - do you have enough leases available?
HOW DO I CHECK THIS?


6. take the cable from one of the working machines and use it on the machine with issues - does this solve the connectivity - if so get a new cable.
I have the same cable conntected to my Laptop now, from where I am posting this message it is not the cable.

7. if not then you are narrowed down to the NIC and the Port you are plugging into - try moving the computer to another port and try again try another NIC in the computer
How do I do this?

I am assuming you are an administrator of your domain, if not you will have to let them know.

1. to check DHCP - open mmc and launch the DHCP plugin for the domain you are in.  and check the scope.

2.  what address did ipconfig give you?

3. csupa is right about the account level, if you are unable to set the IP address manually then you are not logged into the machine as an administrator, however, the fact that you are able to use the same port and cable that the problematic machine is connected to, it could mean that you have a faulty network card.  Assuming of course that your laptop does not have a manual IP address assigned.

4. regarding my point 7 - you said you have your laptop connected so that negates the checking of the port and cable.(otherwise your laptop wouldn't connect)  Still does not rule out a faulty network card in the computer though

hi did 1st scan and takes come up with 3 network adapters

[000000008 ] nVidia nForce Networking Controller (failed)
[000000011 ] Realtek PCIe GBE Family Controller (failed)
[000000013 ] Realtek PCIe GBE Family Controller (passed)

On the second scan DNS server and DHCP server had the same output as above 13 seems to work?

Does this mean windows update installed the wrong driver? And now I have more than 1?

The txt file is unreadable :(

Try this:

1.Boot up one of the other Machines that can connect to the Network type this into run 'ncpa.cpl'
2.Right click on the 'connected' network adapter then go to 'Status' then click the support tab.
3.Jot down the IP address and the Default Gateway.
4. Go back to the problem PC. Network Connections ('Ncpa.cpl' in run), right click the problem network adapter then >Properties>(highlight)Internet Protocol>[Click Button] Properties>Click 'Alternate Configuration'
5. Enter IP Address of the working pc you jotted down but change the last digit to some thing like 5 or 6
EG: If it was 192.168.0.2 change to 192.168.0.5  Subnet Mask should be 255.255.255.0 then enter the Default Gateway as jotted down from the other pc. the hit OK.

6. Run ipconfig /release  then  ipconfig /renew

Any Luck?

If not. Try Restarting the PC.

If still no luck i'd even give the Network Setup Wizard a shot.  Type 'netsetup' into run and follow the instructions.

OK I did a manual configure and the ip now stays as it should.
But when I do ipconfig /release
ipconfig /release and renew say: The operation failed as no adapter is in the state permissible for this operation

It says connected and I try to renew from the interface it works but the problem still there.

to get on the internet the Ip address is not enough information to be entered in manually.  You will also need to add the following information:
1. gateway address
2. DNS server address

If you are manually configuring the computer, make sure you dont give it an IP address already in use by another machine on your network.

You mentioned that your laptop works when you connect it to the cable that was used by the desktop;
1.  from your laptop do an ipconfig /all and find out what IP address scheme are you using. e.g. (192.168.1.x or 10.10.10.x or something else)
2. is your laptop getting a DHCP supplied address or is manually assigned?
3. Has the network ever worked on this desktop?
4. Where is the DHCP server ?  e.g. on the server, router etc.

If you dont get an IP address from your DHCP server the network card uses its own address of 169.x.x.x  this will not work on your network as you have found out.

Hi Cat,

Sorry, to be ObviousMan, but you have a problem caused by a Windows Update.

If you can find which updates installed immediately before your problem, remove (uninstall) them (and make a note of their KB number, so you can determine whether you can safely re-install them, of if you need to make other adjustments in your settings/options).  Otherwise, see if you have a restore point that is just before the update was installed, and restore to that date.  This will not bother any of your data files.

There are several Win Updates that effectively disable Internet access on some computers.  One famous one did so on all Zone Alarm firewall-protected PC's.  Another one installed driver-specific updates that disabled the Ethernet adapter.  There have been several reports of one of the recent March/April 2010 updates that cause Internet access problems.  One of the recent Win updates changes a number of parameters in Internet Explorer 7 and 8, as well as other process/programs from MS that are Internet-aware.

Finally, it is always possible that you have a bad bug on this pc and it is interfering / conflicting with a Win Update meant to protect against that vulnerability.  It is just an unlikely coincidence that this would happen immediately following a Windows Update.  Nevertheless, a really good resource to use is to run MalwareBytes, which you can get from http://www.malwarebytes.org/mbam.php  .   Be sure to heed their suggestions to rename the program before you install it.  I usually download to another PC, burn a CD with the aliased program name, and load it into the target PC from there.  You will want to copy it to the target in Safe Mode, and I think you can install it there too, but you reboot and run it in Normal Mode.  Be sure to do Shut Down, remove the power plug for 30 sec, and then start up to dump anything hanging around in the RAM.  (But do this AFTER the steps in the first two paragraphs above do not work.  No sense in chasing ghosts.)

G'Luck

Cat...state:

To view your updates, go to Start/ControlPanel/Add-or-Remove-Programs.  Check the box at the top "Show updates" and the updates will populate at the bottom of the list.  The uninstall routines are also contained in folders (with dates "Modified") in your c:\Windows directory, and are at the top of the folder list (if you have "Show hidden files and folders" checked in the Tools/FolderOptions/View-tab menu item of Windows Explorer -- you may want to click Apply to all Folders in the General Tab of Folder Options after you make the change).  You can use this list to see when the KB was last installed.

If this pc has Automatic Updates set to ON, it will automatically download and install Windows updates.  Some of the updates actually require a reboot to finish the installation.

I am with jtru on this.  This issue has nothing to do with your network setup.  As you have concluded the system was working fine until a new windows update caused it to stop working.

Do you have any other machines with the same configuration e.g. same NIC, motherboard etc.?
Have you checked these machines to determine if these are effected?  - i say this, because of the other machines are not effected then it "might" not be a windows issue at all and it could be that your NIC was faulty and after the latest update the fault was recognised and hence the issue.

have you tried swapping the NIC out for one from a known working machine? - you might even find that the shutdown/removal/shutdown/install cycle might clear your issue up.

Hi,
I tried "show updates" on the day.
But there was nothing for the day that it happend.
This motherboard is new, as the previous power supply blew the mobo.

I think it could be the driver for the NIC.

The two computers on the network had viruses around the same time

You said the powersupply blew the motherboard - how long ago did this happen?  I have seen it where a blown motherboard has taken out all the PCI cards as well - e.g. video and NICS.

I would initially swap out the NIC with a known working one, just to rule the NIC out of the equation completely, before checking anything else out.  It would be a real pain(for you) to find out at the end of all this trouble shooting that the NIC needed replacing.  :-)

+1 for that,

I scrolled down this whole post to see if it was not suggested but cmorffew just said it. I too believe it to be a failing NIC.

Since you are concerned the NIC may be bad, here is an easy way to test it, without buying a new one, having to figure out how to disable the on-board NIC, and loading the drivers if XP doesn't recognize them.

Just boot the suspect PC with a Linux live CD and see if Linux recognizes the NIC and can reach the Internet.  If it doesn't work, you can always try a new NIC and/or troubleshoot upstream problems.  However, if it works you know your NIC is good and your Ethernet wiring, cable, switch port, etc. are all good, too.  (Say, did you plug in another PC or laptop using the same cable that plugs into your suspect PC?)

To run the LinuxMint live CD, do the following,

1. Shutdown the suspect PC.  Restart it and press F2 during the boot (many pc's) to go into Setup of the BIOS.  Make sure that Boot from CD is the first boot choice.  Press the CD button, so it will open the tray.  Save and Exit.  Hit the power button during boot to shutdown (or shutdown from Windows if you miss it).
2. On another PC, go to http://www.linuxmint.com/ and download the Live CD iso image.  Burn it to a CD.
3. Place the LinuxMint live CD on the open tray of the suspect PC and hit the power button to reboot.  It will boot Linuxmint (a handy distribution based on Ubuntu, by the way).  LinuxMint will install the proper drivers for most Ethernet adapters and do DHCP by default on each interface.  If you actually have more than one interface, you may have to make them active one at a time (Network).  Linux is now running, not Windows, but you will be able to see directories on your hard disk and use the Ethernet interface (eth0, 1, etc.)
4.  When you get the desktop up, you will see an icon along the top that is Firefox browser.  Click it to open Firefox, and if you connect, you are good to go.  Your NIC is fine, the cable, jack, horizontal cable, patch, and switch are all intact and your problem is with Windows.

If not, you can use the Network application to check the IP address.  If it is 169.x.x.x, I would say the NIC is likely good, but you have a connectivity problem to the DHCP server (check cable, etc.).  Switch ports do go out, by the way!  If you have some other error, then the NIC is probably bad.  Be sure to check for multiple NICs.  You can also open the Terminal application and type "ifconfig -a" to display the type of stuff that ipconfig gives in Win.  If it shows more than one interface (eth0 and eth1, for example, you can use a command like "ifconfig eth0 down" to deactivate and then "ifconfig eth1 up" to activate the other interface, or you can just shutdown and remove the extra card.  (Terminal is the real Linux command prompt and it is very different from Windows, so don't screw around here.)  Type "exit" or "quit" to exit Terminal and then you can find the shutdown command for Linux on the System menu.

jtru - how can it be the connectivity to the DHCP server, when the Authors laptop will connect at the same location, using the same cable and port, using DHCP?

Cat...state:, what motherboard did you get?

 I am also wondering if your DHCP server is only set-up to issue IP Address's to known MAC's.  i.e. if your mac address for the NIC is not in the DHCP reservation list - then you wont get an IP address.

Can you get access to the DHCP server or find out how the DHCP server is configured?  If it is configured to only give out Address's to reservations, then you need to get the mac address for the on-board NIC and supply it to the DHCP admin so they can add it to the reservation list for that computer.

Didn't see he had tested the cable/port with another computer, sorry.

Besides, I was just enumerating all the possibilities.  Lots of people scan these answers, and the next person's problem may be slightly different.  I have had a Netgear 24-port 10/100 Layer 2 switch that would just stop passing data on certain ports.  A POR would reset it.  Replaced the switch and it has been stable for 3+ years.  Sometimes the simplest answer is the right one, to quote the sage.

Your point about an ACL, access control list, on the DHCP server is well taken.  He could also set a manual IP address on the NIC in the subnet range and start a ping test to various places, starting with the gateway.  However, the 169.254.x.x address doesn't really tell you much; could be DHCP or connectivity.  I think the Linux test of the NIC is an important troubleshooting step.  You can chase your tail on this sort of thing.

jtru - wasnt meant to offend. :-)  I think we are running out of options for Cat...state.  I agree with you on the NIC testing though.  Now that we know that the NIC is onboard, one would have to "assume" that as the MB is new then the NIC must be ok.

Cat...state: ignoring the steps and advice given so far, have you been able to manually configure the NIC with an IP address, subnet, gateway and DNS server.  I know you were able to add an IP address (RE: approx post 19/20) but could not connect to internet.

try again - as you did say that it showed as connected.  make sure your IP address is correct and not in use on the network before assigning.  e.g. from your laptop ping the address you want to assign to the desktop and see if there is a response - if there is then try another IP address until you get no response.  then copy the settings you get on your laptop for ipconfig /all. i.e. DNS server, Gateway and subnet.
