Cannot Connect to Internet After Installing Service Pack 2

You'll find if you uninstall SP2 your connection will run perfectly as before.  Limited or no connectivity warning
If you see a "limited or no connectivity" warning and a yellow exclamation mark in Device Manager, this only means that the computer's network port is set to automatically obtain an IP address through DHCP (Dynamic Host Configuration Protocol), but a DHCP server could not be found. Windows then generates an APIPA address in the 169.254.x.y range (see chapter APIPA Addresses in Private IP Addresses). This means that all computers in the LAN (Local Area Network) can communicate with each other, if the others also gave themselves APIPA addresses, but you cannot have any Internet connectivity that way.

Try the following as I did:

1) Always with a broadband connection, do these steps first:  Shut down modem - remove power.  Shut down router - remove power.  Shut down computers.  After one minute, restart modem.  When it has fully booted, start the router.  When the modem has fully booted, start all the computers.

2) Go to Start / Run at the command box enter: netsh int ip reset C:\resetlog.txt   ( When you run the reset command it rewrites pertinent registry keys that are used by the Internet Protocol (TCP/IP) stack to reach the same result as the removal and the reinstallation of the protocol.)

3) Go to Local Area Connection and right click on Properties.  Uncheck the QoS Packet Scheduler.  Hopefully this will get you connected.  

Or, maybe this might pertain to you as a last attempt.   address 0.0.0.0

First of all, disable and re-enable the connection. When you change the IP address from automatic to a fixed IP address while the adapter is not connected, you always get a 0.0.0.0 address at first when the adapter reconnects. If this doesn't solve the problem, read on.

Symptoms:

• You cannot obtain an IP address from the DHCP server. The IP address is 0.0.0.0.
• The DHCP service is not running, although it is set to Start Automatic.
• When you try to start the DHCP service, you get the error message: Could not start the DHCP Client Service on Local Computer. Error 1075: The dependency service does not exist or has been marked for deletion.

This problem can occur after uninstalling Norton AntiVirus, which sets the DHCP service as depending on itself. It can also occur when the computer name of the client computer is too long. Make sure that all computer names in your network are no longer than 15 characters.

First set a restore point, so you can undo your changes, should anything go wrong (Programs, Accessories, System programs, System restore).

After setting the restore point, to remove this dependency, do this:

• Click: Start
• Click: Run...
• Type: regedit
• Click: OK
• Navigate to the following keys in the registry:
  HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\DHCP
  HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NetBT
• For each of these, on the right side, double-click: DependOnService
• Delete any lines containing either SYMTDI or NISDRV.
• Click: OK
• Close the Registry Editor.
• Reboot.  http://www.michna.com/kb/WxSP2.htm  http://www.michna.com/kb/WxNetwork.htm

All I know is that after changing the network properties settings "unchecking the Packet Scheduler" I was able to connect finally.

Well, as I said in my post, I did a system restore, therefore, restoring my system to the day before the Service Pack 2 was installed and  then I had no problem with connecting to the internet.  I have a dialup connection.  I no longer have the Service Pack 2 , but will eventually need to install it and need to know why I could not connect  when the Service Pack 2  was on my computer,so that the problem will be resolved when I install again. The things that you talked about in your response to me are utterly Greek. I know absolutely nothing about what you were talking about.  I am not computer literate.

Okay.  Are you using AOL for dial-up?

No, I do not use AOL.  I use MSN as my ISP.  I have MSN 9.  I also created a manual dialup that I use when downloading or when I am idle for a time online, since MSN 9 will disconnect me from the internet if I am idle for 20 minutes. So , when I am going to spend a lot of time reading or being idle , I use the manual dial-up.  But either way, MSN is my ISP .

 

Thanks,

Jillian

Try turning off the QoS Packet Scheduler. 

To do so, click Start, then All Programs, then Accessories, then Communications, and then Network Connections. Right click your network/internet connection, then click Properties.  Uncheck the QoS Packet Scheduler, and try again.  If the QoS option is grayed out, simply click on it and choose the Uninstall button instead.  Otherwise you might want to try MS support located here:

What does the QoS Packet Scheduler do ? What is it's function ? I need to know what the purpose of a service  is before turning it off.  Also , after giving me these instructions , you said " try again" .  Just what am I trying to do  again?  Please be specific, because in all honesty, I don't know what you mean when telling me to try again. As I  can connect to internet with No problems and certainly not going to install Service Pack 2 until I know why I cannot connect after install, so just what are you talking about when you tell me to "try again?"

 

PS.  Followed the instructions and it told me that my internet connection uses the QoS Packet Scheduler.  If I uninstall this, I cannot connect to the internet with MSN>  So , I don't think that uninstalling this will be an option for me.

 

Thanks,

jillian

Thanks, perhaps they can.

jillian,

Maybe someone else can try to help you with your problem.  Have a nice day.

Thanks much for your very helpful guidance.  My Dell 4300 was giving me fits with the "limited or no connectivity" message after upgrading to SP2.  Microsoft Level 1 support staff was unable to help, and I gave up in disgust after 1 1/2 hours of waiting for Level 2 to answer.   Over the next two weeks I re-tried SP2 and backed out three times, following various useless online "cures".  Finally I decided to pick up an inexpensive USB WiFi adapter so the Dell could connect "over the air" to my wireless router in lieu of using the Cat 5 cable - at least until I could get some good advice.  That sneaky workaround got me up and running with SP2 just fine. Then your advice came along and solved the problem first time, so now the Dell is back hardwired to the router.  Hey Jillian - it's worth a try.
