Mostly in such situation the homepage wouldn’t show up however the console page works just fine.
There are a number of well-known Windows programs which use port 80:
The most likely culprit is Microsoft Internet Information Server.
SQL Server Reporting Services
SSRS can remain active even if you uninstall SQL Server. To stop the service:
- Open SQL Server Configuration Manager.
- Select “SQL Server Services” in the left-hand pane.
- Double-click “SQL Server Reporting Services”.
- Hit Stop.
- Switch to the Service tab and set the Start Mode to “Manual”.
You can also stop the services from services.msc
Whats Using Port 80?
Further detective work is necessary if IIS and SSRS are not to blame. Enter the following on the command line:
The active TCP addresses and ports will be listed — locate the line with local address “0.0.0.0:80″ and note the PID value.
Now right-click the task bar and select Start Task Manager. Navigate to the Processes tab and, if necessary, click View > Select Columns… to ensure “PID (Process Identifier)” is checked. You can now locate the PID you noted above. The description and properties should help you determine which application is using the port.
The Task Manager allows you to kill the process, but be a little wary about doing that — especially if it’s “NT Kernel & System”.
I Hope this would be helpful at some instances
