Question:
What might be causing the error BDE 12550
Invalid configuration parameter?
Answer:
12550 Invalid configuration parameter.
One possible cause for the error:
ODBC ALIASES.
When creating and/or using a BDE alias that is using
an ODBC DSN make sure that the ALIAS parameter "ODBC DSN" is
set to the DSN that you wish to use and that has been created
using ODBC Manager. Available ODBC DSN's can be chosen from
the parameter's drop-down edit using the BDE Administrator.
Another possible cause:
Using ISAPI app and ODBC against NT web server.
ODBC DSN on NT machine should be set to "system"
instead of "user".
