I recently installed windows server 2003 enterprise edition, evaluation version on a pantium III machin and I forgot to activate the product within14 days time limit for activation. Now I can´t log on and instead I am directed to a dialog box for acivating the product. But when I enter the product key as I am asked, It says that the product key is invalid and give me the option to visit Microsoft website for more infomation which I couldn´t find proper solution. Any good advise is highly appreciated. Nader

How can I activate my server OS after the time limit for activation has been expired?

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.
