For anyone else that runs into this, we needed a .pm file from the vendor, which I had to install through the iDRAC. Once this was done, Windows activated automatically. Really wish the vendors or Dell could've told me this two months ago...
We have a R720 that's out of warranty and it's motherboard failed, so we ordered a replacement direct from Dell. After replacement, Server 2008 lost it's activation. We've tried everything to get it activated again, including re-imaging, but we are unable to get it to go. Any suggestions? Thanks.
