Not sure if this will help but when I go in to IIS and click on bindings on the faulty HAP machine it lists only http and https where as on the working server it also lists net.tcp net.pipe net.msmq msmq.formatname.

I have also removed the IIS role and re-installed.

Hope someone can help.

Just done a fix on the .net install which seems to have fixed this issue.
