If you install the puppetlabs-dsc module it installs the xSharepoint DSC Resources into the wrong folder.
I installed it inside my demo environment into production:
If you classify a node with my Sharepoint 2013 test manifest file https://github.com/Andulla/dsc_collection/blob/master/manifests/sharepoint2013.pp it will fail as it will not find the DSC resource locally.
For me to fix the bug in my test environment it helped to move the files&folders from /etc/puppetlabs/code/environments/production/modules/dsc/lib/puppet_x/dsc_resources/xSharepoint/Modules/xSharepoint to /etc/puppetlabs/code/environments/production/modulesdsc/lib/puppet_x/dsc_resources/xSharepoint
after that and a plugin sync it was possible to install Sharepoint2013 on WS2008R2. We need to fix this as right now you can't use any of the DSC xSharepoint resources.
