I have been following the thread from people with similar problems but mine is not fixed. This all happened yesterday when AVG falsely identified Zone Alarm as a Trojan and the 'Resident Shield' collected 350,000 examples as Zone Alarm ran all night. I uninstalled both AVG and Zone alarm but since then I am unable to browse the internet for longer than a few minutes. A reboot then restores access for a few minutes.
I have tried everything. I can access email and ftp. I can ping to URL and IP but cannot browse to either (therefore not DNS?) I have tried to fix with winsockxpfix but no effect. Have used netsh reset winsock catalogue no effect.
The effect occurs on different networks. I am using XP + SP2. Have used SP2 winsock fix also.
Could it be TCP/IP stack? Or corruptred browser? Tried system restore - no use.
Had the same problem... Firefox seemed to work, not Chrome nor IE.
In IE I went under Tools->Internet Options->Connections Tab->Lan Settings
Removed check mark next to Use a proxy server...
Put check mark next to Automatic ...

Here are a few more things you can try. They might help :)
click on start, run, enter 'services.msc'
look for DHCP client....
if it says acquiring network address that means that the dhcp client is DISABLED OR STOPTED... highlight the DHCP client and on the left side you will see "START" the service, click on it and then it will say "STOP, RESTART" then double click on the service and on the startup type select automatic, apply
DHCP Client Service may not start automatically. When you attempt to start the Service manually, the following error may be displayed:
Error: Could not start the DHCP Client Service on local computer
Error 1068: The dependency service or group failed to start.
The DHCP Client Service in Windows XP, depends on these three components:
* NetBios over Tcpip
* TCP/IP Protocol Driver
If one of the above drivers fail to start, then the DHCP Client Service may not start.
Step I - Make sure that the three driver files are present
Open Windows Explorer and navigate to /Windir/System32Drivers folder. Make sure that the following files are present in the folder:
If one or more of the above driver files are missing, extract them from the Windows XP CD-ROM or from the ServicePackFilesi386 folder, whichever is the latest version.
Step II - Verify the number of Dependencies
From other sources in the Web, I've found that some versions of Norton Antivirus (NAV) adds an entry to the DHCP Service Dependencies, and removing NAV does not remove the appropriate value from the DHCP Dependencies.
To quickly determine the Dependency services for DHCP Client Service, type the following command in Start, Run dialog:
If additional entries are listed under DEPENDENCIES...
If any other additional drivers or Services are mentioned in the DEPENDENCIES section, you need to remove them via the registry. Follow these steps:
* Click Start, Run and type Regedit.exe
* Navigate to the following branch:
* Backup the branch to a REG file
HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services Dhcp
* Double-click DependOnService MULTI_SZ value and set it's data as follows:
* Close Regedit.exe
Step III - Verify that the Dependency Service / components are running
Next step is to verify that the three dependency components are running. As the three components are actually the Kernel Drivers (Driver Service), you need to manage then via the Device Manager. Follow these steps:
* Click Start, Run and type DEVMGMT.MSC
* In the View menu, click Show hidden devices
* Double-click Non-Plug and Play drivers section
* Double-click the entry - AFD Networking Support Environment, and click the Driver tab
* Set the Startup type to System.
* Start the service. Note down the error message if any.
* Similarly start the two other drivers namely:
