I have three site collections that show up on the site collection lists in Central Admin but do not seem to exist. The browser shows web page not found. Get-SPSite shows the site collections as existing but has a null value for the database property. Whenever I try and manipulate the site collection in any way, I get an, "Object reference not set to an instance of an object." This includes various actions with PowerShell and the GUI. The ULS logs show more of the same, "Object reference not set to an instance of an object." This is only a test environment but test pretty much mimics production and I need to figure out what happened.
Thanks for any thoughts you might have
