WebDev.WebServer.exe has stopped working

[Graeme]

Hi,

I have a fresh Server 2008 running as a workstation, with VS 2008, .NET 3.5, ASP Ajax and RAD controls "Prometheus" installed. When I try to launch the Prometheus examples I get a dialogue stating that the WebDev.WebServer.exe has stopped working.

Another machine I have here, same configuration does not display the error but I cannot open the examples either.

Any help ?

Regards

Graeme

Just to add, I have also installed the RAD silverlight controls on my machine that gets the pop-up error.

Hi Graeme,

Could you please check your server event log. Maybe there is information about the problem in the Application log.

Best wishes,

I get this error when trying to start the examples as well -- application log info:

If I debug in the Microsoft CLR Debugger, this is the exception message:

An unhandled exception of type 'System.Net.Sockets.SocketException' occurred in System.dll

Additional information: Only one usage of each socket address (protocol/network address/port) is normally permitted

Hello,

Thank you for the additional information provided. Because of the error you received, we suppose that you had already started the examples on cassini server. Could you please go to the system tray and close the cassini server? Then, try to start the examples again.

Hope this helps.

Helen,

Thank you, that was it.

Perhaps StartExamples.exe should query for a cassini instance before attempting to initiate another instance on the same port.

Thanks,
Timothy
