Hello Helen,


Using isql command line I can connect without a problem.


Thank you very much Helen, you have saved my day.  I did a search and found the culprit.


I installed iVMS-4200 Stream Media Server (for CCTV) last night just before I went to bed, and I see that they are making use of most probably Interbase.  I will uninstall the software, and see if it resolves my problem.


Thank you again for pointing me in the right direction.

What happens when you try to connect using isql from the \bin directory of your Firebird 2.5.3 root?

My guess is that either you have a rogue copy of either an old Firebird client or an InterBase client in the service path.
