If Windows (7) port 80 unexpectedly becomes blocked then it could be due to a recent installation of Microsoft SQL Server. MSSQL might enable the MSSQL Report Writer service and disabling that service may fix the problem. The service named "Web Deployment Agent" Service may also be causing the port 80 block. Disabling either of these two services should fix the problem.
