Visual InterDev
An error occurred during the debugger's attempt to set up debugging on the server (details are displayed in the dialog box). The debugger can attempt again to enable debugging on the server. However, unless the error condition has been corrected, the setup might fail again.
If errors persist, you can enable debugging on the server manually.
Do you want to continue launching the debugger? If you choose Yes, you can view the file in the debugger and in the browser, but will not be able to debug.
For details about server debugging options, see Debugging Server Script. For information about manually enabling debugging on the server, see the topic "Enabling ASP Debugging on the Server" in Troubleshooting.
