Could not find server! I suddenly started to get these errors.
Upon sharing this problem to a friend of mine, she recommended using Open DNS to solve the problem. It seems that my internet service provider (SmartBro) is having some trouble with their Domain Name Servers. This problem, according to my friend, also frequently happens to PLDT MyDSL as well. Luckily, this is easily solved.
To use Open DNS, go to www.OpenDNS.com and select two IP addresses. Write down these two IP addresses, or copy them to a text editor.
Now, if you're using Windows XP, go to your network connections and choose Properties. Click on TCP/CP and then choose Properties again.
It should reveal a Preferred DNS field. Fill in the two fields with the two IP addresses you got from www.OpenDNS.com.
It solved the problem for three of my computers!
