Hi everyone, I have a peculiar problem. I have a windows xp sp3 machine. It is on our company domain. The domain is managed by our operations center. This machine is creating problems downloading mails via our official mail client. So i thought to upgrade xp by running sp3 patch which i had downloaded. But i was unable to run the patch. I am getting an error that says insufficient priviledges contact your system administrator. I was logged in to the administrator account. Also while installing other software i get the same error. What could be the problem. Some other machines are unable to download attachments sent via mail.
