Problem with accessing Informix command line tools

Hi, we are using Informix Online Workgroup Server 7.22 for NT with the following configuration: Online itself is installed on the primary domain server, I'm trying to access the command line tools ( dbaccess, onstat) from another stand alone server. I always get ( being Admin or informix): Could not initialize the security subsystem: Please ensure that this account has the necessary privileges. The user informix should have the necessary rights (Log on locally, network access), so what's wrong ? I can use ilogin32 without any problems from the stand alone server. From the primary domain server I'm able to run the command line tools, too. Any help is welcome. Regards, Michael Kramer
