So my Red Hat Network Alert Notification Tool is telling me there are two updates waiting for me with its red exclamation point icon. So I click it, run up2date, and it tells me there are no updates (even though there are two right there in the list). So I run "yum upgrade" and it also tells me there are no upgrades. The upgrades in the list are samba-client and samba-common. Is there some reason they are showing up on the RHNANT but running up2date and yum yield no results?
