Datatransferservice CDTS Job DTS Job Bits Errorcode 0x801901F4

Question

I have a new build of Server 2012 R2, SCCM 2012 R2 CU2, and SQL 2012 SP1 CU6. This same set of software works on another network. On the new network, I'm not been able to get any updates working that come through All Software Updates. 3rd Party Updates that
come through Application Management do work. On this new network, the patches appear in WSUS and the SUP. I can make Software Update Groups and Packages. I'm testing them actually deploying and installing  on clients and that doesn't work (2 WIN 7 workstations
and 2 Server 2012 servers). New folders will appear under c:\windows\ccmcache with *.tmp files under them, but the full files won't download and hence do not appear in Software Center. All the clients I'm testing with have the same pair of lines reappearing
in DataTransferService.log:
CDTSJob::HandleErrors: DTS Job '{a guid}' BITS Job '{a GUID}' under user 'a SID' Olderrorcount 111 newerrorcount 112 ErrorCode 0x801901F4
CDTSJOB::HandleErrors: DTS Job ID='{GUID}' URL=server.fqdn/pathtoDP ProtType=1
I've compared the IIS settings on the working network to this one and not yet found a difference. I've also so far found little help via google.
Any input appreciated.

No, it's not the same, but very close. For one thing, this is a different folder. Since our purpose is to share info on fixing tech problems, I thought it best to put this one up too.
As for reappearing, it didn't. The same basic problem appeared on a different folder. To find which folder is the errant one, go to IIS, click in turn on each DP site, click the browse button on the right and if it's this permission problem, it will tell
you in bright red at the top of the web page and give you the path to the problematic folder. Then just change that folder's permissions as needed.
