Error 1016 after moving diagnostics log files

Hi,

I tried to move all log files, including diagnostics log files, to another drive. Now I changed all of them back to their original location. Log folders are created again in the right place.

Also changed the REG key HKLM\Software\Microsoft\ExchangeServer\v15\Diagnostics\LogFolderPath back to 'C:\Program Files\Microsoft\Exchange Server\V15\Logging\Diagnostics'.

Since I did this I get an error every few minutes:
Event ID: 1016
Source: MSExchangeDiagnostics
Error: Unable to match any connection strings from AD. SqlOutputStream: Cannot find connection string that matches site 'Default-First-Site-Name' with version '3.0' in the list of connection strings. Count: '0' Value(s):

Any idea how to fix this?

BR,
Frank
