This is a problem I have sometimes. When updates are available, use the Red Hat Network Alert Icon under Apps ---> System Tools. Double click on the icon (it should be red with an !) to see what's for update. Close the window without doing anything, then reboot the machine (sometimes this problem is caused by leaving the machine on too long) and once you're back in Linux, head to the Terminal (also under System Tools) then become root by typing su plus your password. Type yum update and it should work. Let me know if this doesn't - there are other solutions besides this one, but this is the one to try first. Jared
