Bit of a weird one here. I have a freshly installed and configured SCCM 2012 R2 SP1 setup.
I can get the server to push Packages out (I have one that copies CMTrace.exe to the windows directory and another that uninstalls some software).
I have then setup an application to install Office 2010, but the client shows this error in CIDownloader.log
<![LOG[CIDownloaderJob({4C655596-B3B7-46FE-970E-20F9BBF9F447}): DownloadPackages failed (0x80070003).]LOG]!><time="13:52:43.621-600" date="06-23-2015" component="CIDownloader" context="" type="3" thread="3092" file="packageloaderjob.cpp:1548"><![LOG[CIDownloaderJob({4C655596-B3B7-46FE-970E-20F9BBF9F447}): StartDownload failed (0x80070003).]LOG]!><time="13:52:43.621-600" date="06-23-2015" component="CIDownloader" context="" type="3" thread="3092" file="packageloaderjob.cpp:1548">And I get a matching error in the monitoring section of the console.
The content is distributed to the DP correctly, and can be seen in the appropriate server directory.
I can't find any matching server side errors for the above client error - there are no failures in SCCM logs that I can see, or in the IIS log file at that time.
I also tried a much smaller and simpler deployment of 7Zip - but got the same errors.
I've checked that the permissions on the shares are correct (as far as I can make them out to be - not 100% certain what they should be). Not sure on the permissions for the directories themselves.
I've checked that 'allow clients to connect anonymously' is ticked on the distribution point
I've tried both with and without a Network Access Account setup
Can't find anything that matches the errors listed above on the Internet.
Anyone have any ideas?
