Hope you restarted Firebird service after config editing.

1. Yes please.

What about DumpFolder ?

2. Created now as per:

Wrong. It creates process dump not related to the crash.

If there really was a crash, you should look for crashdump at DumpFolder.

3. Restarted my Laptop.
4. Ran my front end .NET Application and caught the exception:

Error reading data from the connection.
Error reading data from the connection.
   at FirebirdSql.Data.Client.Managed.Version10.GdsStatement.Fetch()
   at FirebirdSql.Data.FirebirdClient.FbCommand.Fetch()

5. Now checking the DumpFolder found only one file "ZeroConfigService.exe.4128.dmp", created earlier to my running my front end application. The dump summary as under:

Dump Summary
Dump File: ZeroConfigService.exe.4128.dmp : C:\Users\rdsc1\DumpFolder\ZeroConfigService.exe.4128.dmp
Last Write Time: 13-12-2017 17:48:18
Process Name: ZeroConfigService.exe : C:\Program Files\Intel\WiFi\bin\ZeroConfigService.exe
Process Architecture: x64
Exception Code: 0xC0000409
Exception Information: 
Heap Information: Not Present

6. Appears that the DumpFolder registry etc working fine. So deleted this file and ensured the DumpFolder was empty.
7. Ran my front end .NET Application again and got the exception as at Para 4 above.
8. Found the DumpFolder empty.
