InfoPath Dev

 Hi all,

I've created a web-based InfoPath form that can stored data back to a Sql Server2005 database.  Sometimes this form works fine, but most of the time, I got the following error when preview the form in design view: "InfoPath cannot submit the form. An error occurred while the form was being submitted. The data connection file could not be accessed." Similar error message when submitting the form through a browser. 

I've checked Normal 0 false false false EN-US ZH-CN X-NONE MicrosoftInternetExplorer4 "Allow cross domain access for user templates" in SharePoint Central Admin, but this problem still exist.

I'm new to InfoPath, can someone tell me what did I miss here? Any suggestions are greatly appreciated.

P.S.: where do you check the SharePoint log files? 

Thanks,

Krany

to check the logs.

go to your central administration

-> operations

under logging and reporting click on diagonostic logging

there check under the path field at whcich location the logs are stored.

 Qazi - Thanks for your input. I chcked th log files, but nothings seems relevent. Wonder if the log trace has been set up correctly.

Here's an example of what I see in the logs. Should this be the diagnostic logs?
