Quite common (based on all the blog-articles) is to set an Incremental update for all collections that require a fast update.The limit for this is (according to Config Mgr 2012 documentation) roughly 200 collections depending and inaddition the queue will increase with updates.
Use Citrix LTSR Assistant tool to confirm LTSR compliance.
When i check "Collection Properties Membership Rules" I am able to see the two machines which i added with Type "Direct".
But when i double click on the collection it does not show anything.
Enter the value you want and search all the resources you want to select.
Once the collection is created only a single resource is a member: A query requires that AD Discovery has updated the group memberships in the database (full or incremental – both will suffice) and once that is completed the collection has to be updated.
