Recently I came across a strange message in SQL Server Error Log:
“SQL Server failed to set security information on the full-text FilterData directory in the FTData folder. Full-text indexing of some types of documents may fail until this issue is resolved. You will need to repair the SQL Server installation.”.
The error number was 30064 with Severity 17. After a quick check in the web I did not find any information of info on troubleshooting such error and I was definitely was not up for “repairing” my SQL Server installation as the message suggested.
To resolve the problem, check the FTData folder path set in the registry – is the path valid, does the SQL Server Service has enough permissions on that folder, etc. The path to the registry key is:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\<instance id>\Setup\FullTextDefaultPath
In my case it was an invalid path in that folder. Unfortunately I was not aware of how this value got there after all the other paths were valid. Anyway, if you encounter such an error, do not hurry to repair the SQL Server. There might just be a simpler solution.
