TFS Query Error - SQL Server encountered error 0x80070005

Users are receiving the following error after running a query in TFS.

Error: SQL Server encountered error 0x80070005 while communicating with full-text filter daemon host (FDHost) process. Make sure that the FDHost process is running. To re-start the FDHost process, run the sp_fulltext_service 'restart_all_fdhosts' command or restart the SQL Server instance.

FDHost is running and has been restarted. Same error after running a query.

How would I resolve this error?

As it turns out the service wasn't start. The SQL Admin started the service but a new error appeared.

Error: An error has occurred during the full-text query. Common causes include: word-breaking errors or timeout, FDHOST permissions/ACL issues, service account missing privileges, malfunctioning IFilters, communication channel issues with FDHost and sqlservr.exe, etc.
