Question : Wireless Network Security Key

I have a laptop with a wireless connection running Win XP Pro. It has detected a wireless network in my colleagues office installed a while ago. However when I try to connect to it i get  warning message. "Security enabled wireless network. This network requires a network key."  However I can't see were I can't see any options anywhere to enter a network key.  Can anyone advise on this.

thanks.

Another way, right click on your wireless icon, select View Available Wireless Networks, double click on your wireless network and it should prompt you for password. Regards.
