Hopefully that helps.

The server currently has 3.0.33 on it, but it needs at least 3.4 to work with windows 7 computers. Red hat will not be upgrading samba beyond 3.0.33 for their 32bit RH5 users. Thus I am stuck and cannot use yum and the red hat repos to do the upgrade. 

On site directed me to this page to download the rpms, but I am not experienced enough with manually updating a package.
http://ftp.sernet.de/pub/samba/ . I downloaded all the files listed under the 3.6/rhel/5/i386 directory.

Thus I was hoping to find to step by step on how to do the upgrade.

For some reason red hat feels they do not need to support their 32 bit users, which my server is running, and updating the OS does not update certain packages like samba and php. Even though I have paid support with red hat they will not provide support to update the needed packages.

I think RH 5 has a samba 3.x package, or was that only Centos?  I don't recall what version it was intro'd
