IIS + Skype = Unable to bind to the underlying transport for [::]:80

By
The same error hit one of my colleges one year ago and two years ago and so on.
The error is from IIS and sounds like this:
Unable to bind to the underlying transport for [::]:80.
The IP Listen-Only list may contain a reference to an 
interface which may not exist on this machine. 
The data field contains the error number.
From command line we can use “NETSTAT –ano” to see what process is blocking our port.
TCP    0.0.0.0:80             0.0.0.0:0              LISTENING       2288
Once we identify the PID (2288) of the process that use our port we can take a look in the Task Manager and identify the process that is using 80 port. And YES, the process that is using port 80 is SKYPE.
I don’t understand why Skype needs to use port 80. Hate it!

    In order to have Skype *not* use the port 80, do the followings:
    go to Skype -> Tools -> Options -> Advanced -> Connection -> Uncheck the "Use port 80 and 443 for additional incoming connections".
    That's it.

    Because most firewall let port 80 through :-)

Windows Docker Containers can make WIN32 API calls, use COM and ASP.NET WebForms

By
After the last post , I received two interesting questions related to Docker and Windows. People were interested if we do Win32 API calls from a Docker container and if there is support for COM. WIN32 Support To test calls to WIN32 API, let’s try to populate SYSTEM_INFO class. [StructLayout(LayoutKind.Sequential)] public struct SYSTEM_INFO { public uint dwOemId; public uint dwPageSize; public uint lpMinimumApplicationAddress; public uint lpMaximumApplicationAddress; public uint dwActiveProcessorMask; public uint dwNumberOfProcessors; public uint dwProcessorType; public uint dwAllocationGranularity; public uint dwProcessorLevel; public uint dwProcessorRevision; } ... [DllImport("kernel32")] static extern void GetSystemInfo(ref SYSTEM_INFO pSI); ... SYSTEM_INFO pSI = new SYSTEM_INFO(...

Navigating Cloud Strategy after Azure Central US Region Outage

By
 Looking back, July 19, 2024, was challenging for customers using Microsoft Azure or Windows machines. Two major outages affected customers using CrowdStrike Falcon or Microsoft Azure computation resources in the Central US. These two outages affected many people and put many businesses on pause for a few hours or even days. The overlap of these two issues was a nightmare for travellers. In addition to blue screens in the airport terminals, they could not get additional information from the airport website, airline personnel, or the support line because they were affected by the outage in the Central US region or the CrowdStrike outage.   But what happened in reality? A faulty CrowdStrike update affected Windows computers globally, from airports and healthcare to small businesses, affecting over 8.5m computers. Even if the Falson Sensor software defect was identified and a fix deployed shortly after, the recovery took longer. In parallel with CrowdStrike, Microsoft provi...
