This could be related to the permissions for the user accessing DAT (DBXL). Usually that error code occurs when a user tries to perform an action in DBXL for which they have not been granted permissions. Does the error I0033 show any other details? Perhaps in the Event Viewer for Qdabra? (like Ted asked)
Our first step should be to look at the groups that are granted permission. Here’s how to do this:
1. In the Qdabrawebservice folder where DBXL was installed, find the web.config file.
2. Open the file (in a text editor, like Notepad) and look for the following: ReaderGroupAlias, WriterGroupAlias, AdminGroupAlias and DbxlAdminAlias.
3. Each of these Keys will be assigned a value (that is, a group). Make a note of these group names.
4. Then, on the machine where DBXL was installed, look at these groups to see who is a member of which groups. If you’ll be managing DBXL then you’ll need to make sure to be a member of AdminGroupAlias and DbxlAdminAlias
