we made a copy of our current SP 2010 environment to run as a Mockup in a separated network area. (we had this running before, but needed an upgrade to get a similar status as the productive farm). The duplication of the domain controllers, database and application server went well, the CA is running as expected. But the frontend server didn't get a connection to the database. Error in all web applications:

"Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace:

[InvalidOperationException: The farm is unavailable.] Microsoft.SharePoint.Administration.Claims.SPSecurityTokenServiceManager.get_Local() +24815036 Microsoft.SharePoint.IdentityModel.SPTokenCache..ctor() +34 (...)"

I tried running the configuration wizard, there I got the error message

"Failed to detect if the server is joined to a server farm. ..."

I chose to disconnect the server from the farm and try to reconnect it (which was maybe not a good idea?), but it doesn't find the database so a connection is not possible. The database server is running and available.

Any ideas? I can rollback to the status before starting the Config Wizard if necessary.

Many thanks for your help in advance. Let me know if I should post the error message more detailed.

Best regards Sibylla

Looks like something has changed in the way you need to connect to your database-server during your copy-operation.

  • Which database connection string do you use to reconnect your server to the configuration database?
  • Look for a mismatching SQL-Alias in C:\windows\system32\cliconfg.exe -> Alias
  • Thanks for this reply. It looks like something went wrong while creating the copy of the server, we are currently renewing the environment. I will keep this post updated. – Sibylla_B Sep 26 '16 at 10:45

Finally we recreated the full test environment which solved the issue.
