The Windows Firewall in Windows XP is designed to help keep unauthorized users from accessing files and resources on your computer. A firewall is a must-have if you're concerned about your computer's safety.
Unfortunately, the Windows Firewall in Windows XP is far from perfect and can sometimes cause more harm than good, especially if there is another firewall program installed.
Don't disable the Windows Firewall unless you have good reason but if you have another security program performing the same functions, feel free.
Follow the few steps below to disable the Windows Firewall in Windows XP.
Click on Start and then Control Panel.
Click on the Network and Internet Connections link.
Note: If you're viewing the Classic View of Control Panel, double-click on the Network Connections icon and skip to Step 4.
Under the or pick a Control Panel icon section, click on the Network Connections link.
In the Network Connections window, right-click on your network connection and choose Properties.
Note: If you have a "high speed" Internet connection like Cable or DSL, or are on a network of some kind, your network connection will likely be titled Local Area Connection.
Choose the Advanced tab in the Properties window of your network connection.
In the Windows Firewall section under the Advanced tab, click on the Settings... button.
Choose the Off (not recommended) radio button in the Windows Firewall window.
Click OK in this window and click OK again in the Properties window of your network connection.
You can now close the Network Connections window.
Now that the Windows Firewall is disabled, repeat whatever steps caused your problem to see if disabling this option has fixed your problem.
