1. Network Connections > Right-click the connection with an overlaid yellow symbol and click Properties.

2. Click on the “General” tab, highlight “Internet Protocol (TCP/IP)”, and click Properties.

3. Click on the “Alternative Configuration” tab, select the “User configured” radio box.

4. Type 192.168.0.2 in the “IP Address” field.

5. Type 255.255.255.0 in the “Subnet mask” field.

6. Click OK twice > this makes the PC connected! (But it doesn’t necessarily solve the problem, so you might as well just skip it.)

• Set the IP address to be obtained automatically, if it isn’t already (see above).

• Admin Tools > Services > DHCP client > (stop) > (start).

• Reboot modem and router.

• Command prompt: netsh int ip reset all

• Command prompt: netsh winsock reset and reboot.

• Check and test your firewall. Your firewall, especially if its a software firewall like ZoneAlarm, Black Ice, Norton Firewall or something else could be blocking the connection. Disable your firewall and test the connection. You may have to resolve the problem by even uninstalling and reinstalling the firewall.

• Run: sfc /scannow (takes ages), if you get any messages, click Browse and go to c:windowsi386 or i386 folder on Win install disc.

• Run this short Registry fix to complete the update. Type the following lines in Notepad and save the file as FixReg.reg on your desktop, then double click on it to install into your registry. (This is a fix I got from online somewhere, and I’ve never tried it myself, so I give no guarantees for what it does to your computer!)

Windows Registry Editor Version 5.00 

[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesIPSec]
"AssumeUDPEncapsulationContextOnSendRule"=dword:00000002

Reboot your computer.

• Check your network card to make sure its configured correctly and working properly. Many times setting the network card to 10Mbps/Full Duplex will solve this issue. To do this, open Control Panel, System, Device Manager. Go to the properties of the Network card, click on the Advanced tab and find the Link Speed and Duplex section. Change it from Auto Detect to 10Mbps/Full Duplex.

I believe I got this off a work colleague once upon a time. Kudos to the one who wrote it down, even though I have no idea who that person was.
