I installed my site on an IIS8, I got "
Quote:
No connection could be made because the target machine actively refused it 127.0.0.1:1521
the server is old, it had a lot of rules installed on it, also there was a MS Exchange installed on IIS, I tried to remove the server Rules, removed and re-installed IIS. Now I'm getting "

HTTP Error 503. The service is unavailable on IIS


I have tried everything on the internet, but not solving the issue. any solution for this. BTW, I don't care about the Exchange server or the server Rules, if I can reset IIS and/or all server Rules as the appear when first installing windows server, this will be OK

edit
my mistake, the error is "...refused it 127.0.0.1:1521" not "...refused it 127.0.0.1:25". sorry

What I have tried:

I have tried many solutions on the internet. such as adding some code on applicationHost.config, and else.

After checking the logs, I'm seeing

It seems Exchange has not been uninstalled properly. What can you see in IIS management console? Are there some leftovers from Exchange? And in services' console?

1 solution

Uninstall IIS and the Windows Process Activation Service.

Then delete or rename the folders C:\inetpub and C:\Windows\System32\inetsrv (if they still exist).

You can then reinstall IIS, and the configuration should be reset to the default.

"HTTP error 503" is gone now. Now, I am back to the original error
"No connection could be made because the target machine actively refused it 127.0.0.1:25"
Hope you still help me with it. Grateful for your help

You're trying to connect on port 25 (SMTP) instead of port 80 (HTTP) or 443 (HTTPS).

What are you trying to do when the error occurs?

sorry, the error "...refused it 127.0.0.1:1521" not "25".
and I'm browsing for "localhost:8050"

Neither of those look like standard ports for IIS. Have you changed the bindings on the site? Or are you trying to use IIS Express instead?
