SCCM OSD error 0x80091007 hash mismatch with WIM

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.

SCCM 2012: dynamic app install Policy download failed

I had an issue the other day with an application not installing that I had been installing for a long time through the UDI wizard with the MDT Integration with SCCM 2012.  Suddenly it had stopped installing and I got the below error in the SMSTS.log.

Make sure the application is marked for dynamic app install Policy download failed, hr=0x80004005. The operating system reported error 2147500037: Unspecified error

While this error can be caused by symbols such as a comma or ampersand in the application name for me it was because I had changed the application name to a more user-friendly name which in turn broke the UDI as it doesn’t dynamically update application names.  I simply went into the UDI and removed and re-added the application and it started working again.
