I have created a web service and it is working correctly when hosted in Local system
But when I hosted the same application in an IIS server, its working weird.
There is a functionality to download file from client machine to server, but the below code returning the "machine actively refused the system 127.0.0.1...." exception

Dim webReq As System.Net.WebRequest = System.Net.WebRequest.Create(Url)
Dim response As HttpWebResponse = DirectCast(webReq.GetResponse(), HttpWebResponse)
response.Close()

Solution 1

If it works on the local machine, but not remotely, then you have an issue in your code that is masked when the server and client run on the same machine. Hard to know the details, without code. Your web service does not attempt to access the file system, does it ?

Thanks for the suggestions
But I have checked the error log and traced to "Retrieving the COM class factory for component with CLSID failed due to the following error: 80040154."
So I think this may be due to not registering all the DLLs in server.
Correct me if I am wrong

Solution 2

This might be because of:

1. Web Reference URL in config file.
2. Port (I think the port is blocked). I think you should try to PING and telnet on the deployed IP and port.
