I want to Mount an existing ContentDatabase with the following command:
Mount-SPContentDatabase Content_WSS_Name -WebApplication http://name -AssignNewDatabaseId
It runs without an error but says that the site count is 0. I can see the database under Manage Content Databases in Central Admin but the site count is also 0 and no site collection shows up under site collections section.
EDIT: New Database, because i have the same Database connected to another SiteColletion, and want a Copy of this.
