I've created a web application at : test.mycompany.net Then I created a root site collection at : test.mycompany.net (publishing portal template) and 3 site collections :

  1. test.mycompany.net/dev (develop template)
  2. test.mycompany.net/my (mysite template)
  3. test.mycompany.net/team (team site template)

My questions are:

  • Is the test.mycompany.net site collection parent for the three other sites?

I've created a custom master page and using it for test.mycompany.net but the three other sites aster page did't inherit it.

  • Why didn't they get my custom master page?
  • What should I do to get this functionality?

  • didn't work!!! . I don't see the checkbox. And there is no answer for the question : Is the test.mycompany.net site collection parent for the three other sites? Commented Sep 10, 2014 at 9:16
  • Are you creating site collections or new subsites? like /dev, /my and /team looks like you are creating subsites.. If that's the case the above should work.. But if they are site collections, then they are completely independent from root site collection and you need to apply masterpage on each Commented Sep 10, 2014 at 9:19
  • I create the site collection, because there is no template alow me to create site collection with subsite consist of these (mysite, team site, wiki) template. Right? Commented Sep 10, 2014 at 9:25
  • I think you can create subsite for Team site and Wiki.. But Mysite has to be a site collection.. Not sure of course, but I will give it a try.. 2013 or 2010 ? which version are you using ? Commented Sep 10, 2014 at 9:33

A Site Collection cannot have a Parent Site Collection, A Site Collection can only have child Sub-Sites.

So to answer your questions:

  1. 'test.mycompany.net' is not a parent to the other site collections.
  2. It didn't inherit because there is no parent-child relationship. Only subsites would be able to inherit the masterpage.
  3. In order to 'share' a masterpage, you would need to add the masterpage to a feature that you could activate on all 4 site collections. Then any changes made to the masterpage would be applied to all 4 sites.
