Update for RHEL4

Hi Everybody,
I have some RHEL4 and RHEL5 machines, whenever i check for new updates on RHEL4 with up2date, it shows me the update which is for RHEL5 machine and not for RHEL4 machine.On the other RHEL4 machine it shows the correct update (which is for RHEL4)
So i am not able to update it. Can anybody help me out to find if any Configuration is mismatching?

Appreciate your help.

Thanks.

Assuming you have separate subscriptions for updates for each of these systems, the problem is probably at the RHN end. Suggest you log into RHN and check what version of the Redhat OS RHN thinks you have on the problem system.

Thanks a lot for the help Fpmurphy..
I'll log the case and check with RHN.

Thanks again.
