gus-bus Posted May 17, 2017 Report post Posted May 17, 2017 Hello, We recently turned on Multicast within our SCCM environment and have been progressively searching for an answer to the following task sequence error: Task Sequence has failed with error code (0x80091007). In searching through the client workstation's SMSTS.log file we see the following: 1. pDownload->Download(pwszServer, pwszNamespace, pwszRemoteObject, pwszLocalObject, uCacheSize), HRESULT=800706ba (e:\nts_sccm_release\sms\server\mcs\consumer\mcclient.cpp,120) ApplyOperatingSystem 5/16/2017 5:25:34 PM 1712 (0x06B0) 2. Encountered error transfering file (0x800706BA). ApplyOperatingSystem 5/16/2017 5:25:34 PM 1712 (0x06B0) 3. Sending status message: SMS_OSDeployment_PackageDownloadMulticastStatusFail ApplyOperatingSystem 5/16/2017 5:25:34 PM 1712 (0x06B0) Since it is unable to transfer the file via multicast you get the following: 4. Hash could not be matched for the downloded content. Original ContentHash = C61CCE4D5DA21B9A531B268C6690D5A1D79867A1CC428E84E96C9CDDFCE1B94A, Downloaded ContentHash = ApplyOperatingSystem 5/16/2017 5:25:34 PM 1712 (0x06B0) 5. 0L == TS::Utility::VerifyPackageHash (pszContentID, sDestination), HRESULT=80091007 (e:\cm1702_rtm\sms\framework\tscore\resolvesource.cpp,3291) ApplyOperatingSystem 5/16/2017 5:25:34 PM 1712 (0x06B0) 6. DownloadContentAndVerifyHash() failed. 80091007. ApplyOperatingSystem 5/16/2017 5:25:34 PM 1712 (0x06B0) 7. Installation of image 1 in package DL100069 failed to complete.. The hash value is not correct. (Error: 80091007; Source: Windows) ApplyOperatingSystem 5/16/2017 5:25:34 PM 1712 (0x06B0) We've verified the proper core switch configurations for across VLAN multicasting and have also ensured the OS, driver packages, etc are set to "allow multicast" within SCCM. We've also redistributed the content to the distribution points using multicasting to ensure there isn't an issue there. With how quickly it fails it doesn't appear that it is even able to pull the OS multicast file. In looking at the distribution point we have enabled for multicast we see the following in the MCSIsapi.log: 1. Could not create an instance of the MCSISAPIProxy object (0x80070005) McsIsapi 5/16/2017 8:00:03 PM 3000 (0x0BB8) 2. HealthCheckRequest::HandleMessage failed with errorcode (0x80070005) McsIsapi 5/16/2017 8:00:03 PM 3000 (0x0BB8) 3. Failed to process HEALTHCHECK request for client ffffffff-ffff-ffff-ffff-ffffffffffff McsIsapi 5/16/2017 8:00:03 PM 3000 (0x0BB8) 4. MCSRequestHandler::HandleMessage for Op HEALTHCHECK failed with server errorcode 2052 McsIsapi 5/16/2017 8:00:03 PM 3000 (0x0BB8) 5. Looking for: E:\SCCMContentLib\DataLib\DL100069* McsIsapi 5/16/2017 8:06:52 PM 2972 (0x0B9C) 6. Looking for: E:\SCCMContentLib\DataLib\DL100069* McsIsapi 5/16/2017 8:35:22 PM 2972 (0x0B9C) Even though it is looking for that package, the distribution point has it when you search in that location. We've found several forums/articles with people who have similar issues but none of the items they recommend trying to seem to work for us. The closest article to what we are experiencing is the following: http://thoughtsonopsmgr.blogspot.in/2014/08/sccm-2012x-multicast-another-bites-dust.html We are running Configuration Manager 1702 running on Server 2012 R2 x64. All of the distribution points are also on Server 2012 R2 x64. I would also like to add that as soon as we turn off multicast in the distribution point, it works flawlessly on unicast. Any thoughts on where to go on this one would be greatly appreciated. Thanks /Gus Quote Share this post Link to post Share on other sites More sharing options...
