Why Powershell's New-WebBinding commandlet creates incorrect HostHeader? - iis

Question

I am trying to add an MSMQ binding for my IIS Web Site, correct binding should look like this:
So I am executing following line in PowerShell:
New-WebBinding -Name "My Site" -Protocol net.msmq -HostHeader "localhost"
and it creates the following binding:
prefixing it with *:80:, so my MSMQ messages don't get picked up by WCF service. Maybe I am doing it wrong? How to create a binding with Binding Information set to just "localhost" using this PowerShell comandlet?
Commandlet codumentaiton can be found here.

Answer 1

Looking at the decompiled code of the cmdlet, looks like it adding the IPAddress and Port information in the binding and there is no workaround to it.
Relevant sections from the code:
private string ipAddress = "*";
...
builder.Append(this.ipAddress);
...
builder.Append(":" + this.sitePort.ToString(CultureInfo.InvariantCulture) + ":");
But you can do what the cmdlet actually does ( below code from cmdlet):
new-itemproperty -path "IIS:\sites\test" -name bindings -value #{protocol="net.msmq"; bindingInformation="localhost"}

Answer 2

Give this a try:
New-ItemProperty "IIS:\sites\NameOfYourSite" -name bindings -value #{protocol="net.msmq";bindingInformation="localhost"}

Answer 3

If your are running PowerShell (Core), a.k.a PowerShell >v7.1.x, you will find yourself in trouble because...
WARNING: Module WebAdministration is loaded in Windows PowerShell using WinPSCompatSession remoting session;
please note that all input and output of commands from this module will be deserialized objects.
If you want to load this module into PowerShell please use 'Import-Module -SkipEditionCheck' syntax.
The IIS provider isn't available via remoting session.
The easiest trick is to redirect string via pipeline to Windows PowerShell.
"Import-Module WebAdministration;New-ItemProperty -Path `"IIS:\Sites\$($configuration.Website.Name)`" -Name Bindings -value #{protocol = `"net.msmq`"; bindingInformation = `"localhost`" }" | PowerShell
In this example, the website name is read from the configuration JSON. You can replace it by a hard-coded site name.
