When an error is generated in Windows Server 2003, a dialog box will appear asking whether or not you want to send an error report. If you have already sent in a report for a reoccurring problem or if you find this to be an annoyance, you can disable error reporting all together. To accomplish this you have to open the System applet within the Control Panel.
Click Start and click Control Panel.
Double click the System icon.
Go to the Advanced tab.
Click Error Reporting.
Click the “Disable Error Reporting” radio box, but select the “But notify me when Critical Errors Occur.”
