Poweredge 1950 Refuses to update BIOS

I'm having no luck updating the BIOS of a Dell Poweredge 1950. It currently has BIOS version 2.4.5 installed. I'm getting "BIOS Update Failed" on restart.

I tried installing 2.7.0 and then tried 2.6.1 when that didn't work. I also tried opening an elevated command prompt from windows server 2012 R2 and using the /force command when running the BIOS updates. That didn't work either.

Any help?
