Hello All, I would like to share my experience about windows updtate service pack 2 and latest version through proxy. We have observed if Windows XP Professional Version 2002, Service Pack2 has automatica update is enable than squid was not allowing to update windows. We had a lot of communication with microsoft but we could not get proper solution. We were trying by different option. We format our system and installed with Windows XP service Pack1 and turn off automatic update and tried to update and we got succeed. Then, we turn off the window automatic update option and try to update, the system updated successfully. Those who have windows update problem, with squid kindly try. If anyone has some different experience,kindly give me suggestion. Thank you. Jigar ____________________________________________________________________________________ Be a better Heartthrob.
