title: Is this a Windows XP firewall bug?
body: <p>I have a webserver running on my Windows XP computer. I have set the firewall to allow incoming HTTP connections: Firewall settings window->'Advanced' tab->select my network connection->Settings->Services->check 'Webserver(HTTP)' checkbox. </p>
  
  <p>Normally, this works. However, sometimes upon restarting the server machine, the firewall again begins blocking HTTP connections, notwithstanding the fact that the 'Webserver(HTTP)' exception is still checked in the Firewall settings window. </p>
  
  <p>The only way, then, to get things working again is to uncheck the said option, save the settings, reopen the firewall dialog and check the option and save again. </p>
  
  <p>My question is, is this some peculiarity of my machine or is this a Windows XP firewall bug? </p>
