I had been distibuting packages to BDPs across a few SCCM enviornments and after monitoring report 136 I noticed that there were lots of packages still ‘Waiting to install package’ even after a few days . I checked the DataTransferService.log on the problem BDPs and noticed:
DTS::AddTransportSecurityOptionsToBITSJob – Failed to QueryInterface for IBackgroundCopyJobHttpOptions. BITS 2.5+ may not be installed properly.
These BDPs were running Windows 2003 x86 SP2. KB923845 (BITS 2.5) is installed with the SCCM client agent if it isn’t already installed. It isn’t obvious, but to utilise BITS 2.5, the client will require a restart.
I can verify that this needs a restart because within Windows\System32, files like Bitsprx2.dll change from version 6.6.xxx before the restart to 6.7.xxx after the restart. KB923845 (http://support.microsoft.com/kb/923845) indicates that these are the files that are updated in this hotfix.
Once the BDP was restarted, the error went away and the DataTransferService, PeerDPAgent and ContentTransferManager logs all show that data is being processed again.
