This has the hallmark of nss issues (or hard disk failure)
ie: username/group lookup failing, you don't happen to be using ldap by any 
chance?

Anyway, check your  /etc/nsswitch.conf

It should have the following (Also Centos 5.3)

passwd:     files
shadow:     files
group:      files

#hosts:     db files nisplus nis dns
hosts:      files dns
