"Server busy" dialog error using scanner in silverlight

Question

Hi,

My Silverlight application is used to connect to a scanner and scan the images to be saved in database. Using AutomationFactory to create "WIA.CommonDialog" to connect to the scanner. The application works fine if the scan process completes within 30 secs, else a "Server busy" dialog box pops out with the options "Switch To","Retry" and "Cancel"..How to disable this dialog???

Thanks and Regards,
