[Samba] Trying to update samba

[jlee at brewtoncityschools.org]

I have a server running samba-3.0.9-1.3E.10.  And I'm trying to update that so I
can now add windows 7 pcs to my network.  The server is a Dell Poweredge 2850
running Red Hat Enterprise Linux EX release 3 (taroon update 8).  It's also
running Webmin version 1.580.  I wanted to download the update as an .rmp
thinking it would be easier and I would be able to run it from my webmin command
line.  I went to http://rpmfind.net/linux/rpm2html/search.php?query=samba to the
.rmp.  I wasn't sure which one to try so I tried a few.  I would like to stay
away fedora if possible.  I ran the rmp from my command shell using rpm -U
command.  That ended up giving me the error

Then I tried rpm -U --nodeps.  The new error message I received was

error: unpacking of archive failed: cpio: Bad magic




I'm not really familiar with this os so any help would greatly be appreciated.
