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.
Choose Yes if you want the debugger to continue trying to set up debugging. Choose No if you want to enable server debugging manually and don't want the debugger to do so.
For details about server debugging options, see Debugging Server Script.
