Well the call with Dell didn't help, but eventually I was able to figure it out.  I learned that when trying to browse out to a package (executable) for download, IIS would return a 404 error. An example URL was [URL] I had to open up the web.config for the Essentials site and add the following snippey inside the section.             The site's web.config file is located at C:\Program Files\Dell\SysMgt\Essentials\wwwroot\Essentials\. Once that module was in place I was able to browse to any package and it would prompt me to download it. From there, I tested updates out again on the ESXi hosts and all is well again. Hopefully this little bit of information helps someone else! Thanks again for everyone's assistance.
I'm currently running Dell's OME v2.0.  Everything is working great including updates via OMSA. However, updates done via the iDRAC connections fail every time. I could say I have tried everything, but I figured somebody could help me with troubleshooting everything all over again in case I missed something or did something incorrectly.  The DRAC connections live on a different subnet, but there is no firewall between these two networks.  Only a router that routes traffic between the two.  As I type this I came up with a few more ideas, but if you have anything else to offer that would be great.  Here is the error I get when trying to deploy the updates.  Results:   Downloading Packages. Calling InstallFromUri method to Download packages to the iDRAC  Downloading Package: BIOS_V7P04_WN64_2.2.3.EXE onto the iDRAC  Package download has successfully started and the Job ID is JID_121890750543 The URI given to the iDRAC to download from: [URL] the Status on the following Job(s): JID_121890750543The JOBID JID_121890750543 has failed with the following message: The network file transfer of an update package was not successful.MessageID: RED051 Download Error occured.
