During baan user creation .When "convert baan user to
database user" .An error occured.

Err msg:
"Error from database Error 3425 Connect to DB A remote host refused an attempted connect operation"

Anyone Please advised .

Thanks

Is your database server different from your application server? If yes, may be its a problem with login and password you have used in Baan to connect to the database server. Or may be it is a network problem.
