We have been testing and tweaking our Task Sequence for several weeks now and had previously imaged Lenovo T420s's without issue. Yesterday we rebuilt a T420s, a T430s, and Optiplex 760 and a Hyper-V VM. Both T420's fail when they get to a step to install an Application (we disabled the initial app that was failing and experienced the same behavior on any of the Application installs).
Some snippets from smsts.log:
Right before the failure we get "Policy evaluation failed, hr=0x87d00267" followed by "Failed to run the action: Install App123. Download Failed (Error: 87D00267; Source: CCM)"
In the CIDownloader.log at the same time we see:
GenerateDCMUrlPrefix failed (0x87d00269)
CIDownloaderJob({GUID}): DownloadPackages failed (0x87d00269).
CCIDownloaderJob::StartDownload - MP not found - will retry.
CIDownloaderJob({GUID})::CCIdownloader Job::QuueueRetry - Job is set to fail immediately on error - no retries.
CIDownloaderJob({GUID}): QueueRetry failed (0x87d00267).
In the LocationServices log we see multiple entries of the following about two minutes or so before the failure:
Unable to retrieve AD forest + domain membership
Failed to refresh security settings over MP with error 0x8007054b
No security settings update detected
Retrieved lookup MP [PrimarySiteServerFQDN] from Registry

Now having said all this, there are a few "packages" that download and install immediately before the "application" without issue. As soon as it hits the application it fails right away. The applications as it stands are standalone tasks within the TS with a single application specified.
The driver set has not changed for any of the models and are being applied correctly. Again this issue only affecs the T420s. (haven't tested ALL models yet but of the ones we have tested so far this one fails consistently). Again, a few weeks ago we were able to build the T420s fine.
I ran a continous ping to the local MP during the packages installing correctly and the applicaiton failure and it stayed consistent with a <1 ms response.
The only tweaks we have made since last installing (that i can recall for sure) was removing the CCMHOSTNAME parameter from the Setup Windows and ConfigMgr step as the clinet was intermittently flipping over to "internet" and failing to download package. This issue happened on ALL models we tested. Once we removed that and left only SMSMP=MPFQDN SMSCACHSIZE=7000 CCMLOGMAXSIZE=1000000 builds starting working again...that is until we tested the T420s.
Anyone seen this before or have any ideas on what to look for to diagnose this? We have tested several times and the issue is persistent each time on this model. We have removed the object from the ConfigMgr database and AD and rebuilt with the same result. Again we also tested multiple T420s's and get the same result on both. I am thoroughly stumped on what could be causing this.
