Re: DSN Problem w/ ASP.NET
You should try to connect without the DSN if you can. Meaning use a fully Connection String based Connection. Also is there a DataSource configured on the Web Server? That's where it has to be for a Web Based app.
I haven't worked with an AS/400 in 4 or 5 years and I had problems then because we didn't have the correct drivers on our server(Web Server). You also might want to look into the cause being related ASPNET user name and that ASP.Net Try to connect with this.
Sorry I can't be more helpfull. Are you working with DB2?
Re: DSN Problem w/ ASP.NET
I tried both DSN and DSN-less connections to no avail. The desktop machine is the web server so permissions and drivers shouldn't be an issue. I managed to get the app working using OLE, but I would still like to resolve the ODBC issue for future reference...
