Phil, Are you saying the "publish-bcwebcontent" command line would be run against the content library itself through the web interface of the DP? Yup, it needs to run against the content that it’s going to stage. Wouldn't it have to be the DP that these clients would be checking the BC hash against? Nope, your DP’s should all have the same server secret – ConfigMgr takes care of that providing you use ConfigMgr to configure BranchCache. And wouldn't a successful deployment using the branchcache option be needed first, to create the hashes for the content that you would be "manually caching". The hashes get created during the staging process. Do you have to do a piece of content at a time if you were caching it this way? How could you do this in batches for large amounts of content from the library? Up to you how you do it – but yes, tricky due to the way that ConfigMgr abstracts the actual content. It would be kind of all or nothing..i.e you’d have to point to the root of the Content Library and grab the whole thing. OR if you have the content source on a BranchCache-enabled server, you could run the staging command against that – providing it has the same server secret as the DPs, then you could do it easily on a package by package basis if required. Still this might be better than deploying the content to get it into the cache for any static content. Also toyed with deployment availability and deadlines far far into the future to stage the branchcache, but haven't seen that work at scale yet. Other thought I had was to use offline media task sequence deployments to stage the content on branchcache/WinPE peercache peers, but I have no idea if that is supported, or if it would work.

I guess not many use Prestage media, otherwise it would have been noticed that content usage of applications is broken since 1511 (up to 1606). Basically, while the content is there it isn’t used and everything downloaded anyway I’ve opened a case with 1511 and it was confirmed and that a fix doesn’t make it in 1606. Does anyone know about this or any planned fixes? Since it’s broken I was looking for an alternative solution (or workaround): Branchcache. I’ve brought this up in the past and Andreas helped (kind of ☺ ), now I’d like to actually do this: • Export all BC content from the server • Create a package and have it applied during OSD before applications are used (which does work for prestage) • When the content is requested, local BC is used. When this was discussed before it was basically about that: http://2pintsoftware.com/2psfaqs/branchcache-caching-faq/ But I don’t get it. On The Server 1. Stage the Content Publish-BCWebContent -Path c:\inetpub\wwwroot\MyBigWIMFile.WIM -StageData -StagingPath c:\temp That is throwing an error: ObjectNotFound. Isn’t that where the content is: PS U:\> dir C:\Windows\ServiceProfiles\NetworkService\AppData\Local\PeerDistPub Directory: C:\Windows\ServiceProfiles\NetworkService\AppData\Local\PeerDistPub Mode LastWriteTime Length Name ---- ------------- ------ ---- d---- 17.06.2015 13:53 PrimaryHashStore d---- 17.06.2015 13:53 TempHashStore -a--- 09.08.2016 00:08 8192 edb.chk -a--- 09.08.2016 00:08 5242880 edb.log -a--- 09.08.2016 00:08 5242880 edbres00001.jrs -a--- 09.08.2016 00:08 5242880 edbres00002.jrs -a--- 09.08.2016 00:08 5242880 edbtmp.log -a--- 09.08.2016 00:08 8454144 PeerDistPubCatalog.pds PS U:\> dir C:\Windows\ServiceProfiles\NetworkService\AppData\Local\PeerDistRepub Directory: C:\Windows\ServiceProfiles\NetworkService\AppData\Local\PeerDistRepub Mode LastWriteTime Length Name ---- ------------- ------ ---- d---- 17.06.2015 13:53 Store -a--- 30.07.2016 02:46 8192 edb.chk -a--- 30.07.2016 02:46 5242880 edb.log -a--- 17.06.2015 13:53 5242880 edbres00001.jrs -a--- 17.06.2015 13:53 5242880 edbres00002.jrs -a--- 17.06.2015 16:09 5242880 edbtmp.log -a--- 30.07.2016 02:47 8454144 PeerDistRepubStoreCatalog.pds How do I export that content then? 2. Export the content to a package (creates a handy .zip file) Export-BCCachePackage -StagingPath c:\temp -Destination c:\MyBCPackage That would work once 1 works? On The Client 1.Import the Package Created in Step 2 Above Import-BCCachePackage -Path C:\temp\pkg\PeerDistPackage.zip And on Win 7? ..And you’re done! The content and is in the client cache ready for access by other computers, and the hashes are on the server (they get generated during the Staging part). cheers, Roland
