Currently I am trying to run a website from localhost (it is c# application rnning under Visual Studio 2008). Till last week I did not have any issues. All of a sudden I started getting this error as below. Do you know what is causing it? Many thanks in advance.
Could not connect to http://ServerName/xxxx/services/UserAuthService/
. TCP error code 10061: No connection could be made because the target machine actively refused it xx.xx.xx.xxx:80.
