YUM gets abuse of service for server ERROR CODE: 49

Greetings

Its been awhile since I've worked on RHEL 6 but I'm getting this error message whenever I try installing a package using YUM.  I bascially inherit this stuff so i was not part of the build process.  I have some 50 odd VM RHEL 6.4 servers thats been cloned.  When i try to do a YUM install package comes back with AOS that is not the server that i'm using.  Any help would be appreciated.
