回答1:

Find firebird.conf, uncomment (if using fbclient 2.x) and change the following parameters to disable WireCrypt and set higher priority for legacy authentication:

WireCrypt = Disabled
AuthServer = Legacy_Auth, Srp, Win_Sspi
AuthClient = Legacy_Auth, Srp, Win_Sspi

You need to change the Firebird service as follows:

1. Install Firebird
2. Go search Services-> Firebird
3. Right click on Firebird->Properties-> LogOn-> and tick checkbox having option as "Allows services to interact with Desktop"

4. and then click on Restart service

   You are now able to connect with firebird successfully in case of Firebird 2.1.
