There have been many posts regrding this issue, nevertheless I feel that my case is different.
I'm running an SQLServer database on a Windows Server 2003
When I start debugging the application everything is ok.
I start and stop the debugging many times, doing the same testing processing.
Suddenly I can not debug anymore and I get this message
"Could not start debugging on the web server"
If I try to run the app without debugging I get a message:
Retarting the web server wont help
Restarting the Visual Studio IDE creates an error message saying "Service Unavailable"
I need to reboot the server (!!!) in order to be able to continue debugging
