Unable to launch the ASP.NET Development server because port '1900' is in use.
- by Shaul
I don't know what has got into my computer today. I was developing just fine in VS 2008 and testing my ASP.NET web site on my development server.
Then suddenly, out of the blue, I can't run my web site any more! As soon as I hit F5, the message appears: Unable to launch the ASP.NET Development server because port '1900' is in use. And it doesn't matter what port I change to, it's always in use! AAARRRGGGHH!!!
I have tried:
Changing the port number
Restarting Visual Studio
Rebooting my machine
Installing IIS
Clue: My IIS refuses to start. But I didn't have IIS installed when I was happily working earlier, so that is probably not the issue; it might just be highlighting something else...
Thanks in advance...
Update: after rebooting, IIS does start, but the problem here persists.
