I checked the rpms for AS and ES from the redhat network site, and they are both the same file.

The kernel I have upgraded to is; kernel-smp-2.4.21-37.EL The links from the packages both go to the same place... kernel-smp-2.4.21-37.EL.i686 Red Hat Enterprise Linux ES (v. 3 for x86) https://rhn.redhat.com/network/software/packages/details.pxt?pid=327068 kernel-smp-2.4.21-37.EL.i686 Red Hat Enterprise Linux AS (v. 3 for x86) https://rhn.redhat.com/network/software/packages/details.pxt?pid=327068 I noticed that my redhat-release package has been upgraded to the wrong version as well.
