Hi Jesse,
Looks to me like BITS is erroring somewhere in the DL - try this command on the
client to look at the BITS job perhaps?
Bitsadmin.exe /info {insert-bits-guid-from cas.log-here} /verbose
This should point you in the right direction
Thanks
Phil

Subject: [mssms] "IsCacheCopyNeeded returned 'true' by
{5777363A-FB22-4a42-ABB0-522DD42711DC}" during software deployment
I am trying to deploy a rather huge piece of software (SAS 9.4, ~19G) and am
running into some issues with clients not being able to download the content.
The software is being deployed as an application. When I set up a required
deployment for a machine, the machine will see it, see it needs to download
content, and try to start downloading. Around this time, CAS.log will start to
go crazy spamming "IsCacheCopyNeeded returned 'true' by
{5777363A-FB22-4a42-ABB0-522DD42711DC}". It write about 3-5M of this per minute.
While googling around I found this thread:
https://social.technet.microsoft.com/Forums/en-US/ce763dc6-c184-47bf-85a8-463501206000/2012-client-stuck-problem?forum=configmanagergeneral.
There is not much detail but they do reference the "dodgy registry key
IsCacheCopyNeededCallBack" (which is actually a value under
HKLM\SOFTWARE\Microsoft\SMS\Mobile Client\ Software Distribution). Deleting
this value causes the callback to fail, after which the content immediately
starts downloading. It should be noted that machines that are not having these
issues also have this registry value.
Anyone else run into this before? We've pushed a ton of software out with this
site (though this is the largest) and have never run into this until now. I'm
not sure what deleting the registry value does and while it seems to alleviate
the issue, I don't want to cause unexpected issues down the road.
For reference, site and client version are ConfigMgr 2012 R2 CU1. The client
cache size is currently set at 30G.
