WINDOWS TIPS AND TRICK

1. Scan your PC for viruses and spyware. Many of these malicious programs can cause connectivity problems. Run a complete system scan instead of a quick one so that all files on the computer will be checked. Complex viruses can resist removal. These can be removed by restoring the system to a time before the virus/spyware took root.
2. Use System Restore if you can't get rid of the malware. Go to 'Start' and point to 'All Programs,' then choose 'Accessories,' then 'System Tools,' then 'System Restore.' On the Welcome screen, click 'Restore my computer to an earlier time.' If it is already selected, just click 'Next.' On the next page, choose a restore point prior to the time the problems began. If a confirmation message appears, click 'OK.' On the page titled 'Confirm Restore Point Selection,' click 'Next.' When finished, the computer will restart.
3. Check the firewall for blocked ports. Normally, Windows XP's firewall will let you know when a program is being blocked. The 'Windows Security Alert' will pop up and give you three options. If you are sure the program isn't harmful, choose 'Unblock' to allow the connection. You may not see this alert if it has been disabled; this can be changed in the settings.
4. Open the Windows Firewall. Click 'Start' and choose 'Run.' In the box, type 'wscui.cpl,' and then click 'OK.' In the Windows Firewall dialog box, you should see a check mark by 'Display a notification when Windows Firewall blocks a program.' If not, click to add one.
5. Repair the connection automatically. There is a feature in XP that will check the connection and fix problems with the network and ports. To find it, go the 'Control Panel' in the 'Start' menu and open 'Network Connections.' Right-click on the troublesome connection and choose 'Repair.'
