Why does IIS7 restore unwanted MSMQ bindings?

Question

Why does IIS7 keep restoring the following bindings, even after I have removed them?

• net.tcp 808:*
• net.pipe *
• net.msmq localhost
• msmq.formatname localhost

Is this just a property of MSMQ being installed? Can the bindings be disabled without uninstalling MSMQ?

Regards, Rob.

Well, I couldn't find any answers, but my workaround does appear to work.

Locate the file: C:\WINDOWS\System32\inetsrv\config\applicationHost.config

This is effectively the web.config file for all the settings you configure through the IIS Console Manager.

WARNING: Edit at your own risk. If you get this wrong, it will take your IIS server offline until you fix it. You'll know if you have got it wrong, as the IIS Console Manager will give you an error popup when you access a website, telling you it was unable to parse this file.

Locate the section of XML under the element system.applicationHost similar to the following:

    <listenerAdapters>
        <add name="http" />
        <add name="net.tcp" identity="S-0-0-00-0000000000-0000000000-0000000000-0000000000-000000000" />
        <add name="net.pipe" identity="S-0-0-00-0000000000-000000000-0000000000-0000000000-0000000000" />
        <add name="net.msmq" identity="S-0-0-00-00000000-0000000000-0000000000-000000000-0000000000" />
        <add name="msmq.formatname" identity="S-0-0-00-00000000-0000000000-0000000000-000000000-0000000000" />
    </listenerAdapters>

If you comment out the listener adapter entries for the unwanted binding types, this prevents them from being associated with your websites automatically. I.e:

    <listenerAdapters>
        <add name="http" />
        <!--
        <add name="net.tcp" identity="S-0-0-00-0000000000-0000000000-0000000000-0000000000-000000000" />
        <add name="net.pipe" identity="S-0-0-00-0000000000-000000000-0000000000-0000000000-0000000000" />
        <add name="net.msmq" identity="S-0-0-00-00000000-0000000000-0000000000-000000000-0000000000" />
        <add name="msmq.formatname" identity="S-0-0-00-00000000-0000000000-0000000000-000000000-0000000000" />
        -->
    </listenerAdapters>

Note: I have noticed that sometimes these bindings re-appear anyway, but when I looked at this file, it had new entries for these bindings added back into the file. So far, I have never had to comment them out more than twice.
