I came across a TechNet blog post on Microsofts site the other day that taught me something new I thought I would pass along in case it would help someone out. If you don’t have software assurance with Microsoft but are a volume license customer you can deploy volume license media providing you have keys and the edition of the OEM OS and the Volume License match. This means you don’t have to be purchasing volume licenses to reimage provided you do have at least a few volume licenses of the software you are trying to deploy. The below blog posts provide more info. Guess you learn something new every day.
I had a Lenovo x240 laptop that wouldn’t image. Other machines would image just fine so I did what any decent SCCM admin would do I looked at the smsts.log and found an error something like 0x80091007 indicating a hash mismatch between the DP and the WIM on the machine. Normally when this occurs the normal recommendation is to refresh the DP with a new copy of the WIM to make sure the DP doesn’t have a bad copy from the main SCCM server but as other pc’s were imaging fine off the same DP it had to be either with that specific machine or something with that model of PC’s. After digging and getting nowhere I stumbled on this article from thespoo.blogspot.com detailing all the way back in 2010 how a bad ram stick could cause the hash mismatch. So I replaced the RAM and sure enough, it was fixed and I was on its way. Goes to show sometimes the simple things can be the fix. I was looking for something a little more elaborate.
