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:
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.
[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.
