OverviewRan into this issue again recently at an MDT install. Took a few minutes to realize they had an older version of CMTrace on their Deployment Share and PE media. Was trying to track down several OSD deployment issues and befuddled why nothing was in the log after a certain point. Took a bit to figure out the log viewer was the initial fault. Long story short, CMTrace.EXE from ConfigMgr 2012 RTM is limited to seeing 8000 lines in a log. Microsoft has a KB about it here. I originally ran into this issue a while back with ConfigMgr 2012 RTM and even SP1 with PE media that had the RTM version in it.
SolutionSimple, get an updated version from various sources. If you have ConfigMgr 2012 R2 (or SP1) installed you can get the 32-Bit and 64-Bit editions of CMTrace from the ConfigMgr_Root_Folder\OSD\bin\i386 and x64 folders.Even if you are using ConfigMgr RTM or SP1 you can grab the CMTrace in the R2 Toolkit (or the SP1 toolkit) and update your copies.
For PE media, don't forget to get the 32-Bit or 64-Bit one for your architecture since PE does not have SysWow64 in it. I generally recommend to inject it into the PE media. In MDT do it via the Extra folder under the Deployment Share Properties I also put it in the root of the Deployment Share by putting both 32-Bit and 64-Bit versions there for use in once you have switched from PE to the deployed OS. For ConfigMgr OSD you can do via osdinjection.xml.
Johan Arwidmark has a HOWTO to split the two arches from the toolkit.
