I don’t know how, but the website for the Dynamics AX Windows Mobile Device Portal on my AX 2012 R3 CU8 solution demo virtual machine occasionally becomes bound to port 0.This seems to annoy IIS, and as a result I get ‘This page can’t be displayed’ when I attempt to visit the mobile device portal:
In IIS Manager, I can see that this is because the site is stopped:
Attempting to start the site produces the error ‘Value does not fall within the expected range.’:
If you track down the cause of the error, you will find that it is because the site is bound to port 0. It is easy to fix this in IIS:
After removing that particular binding, the mobile device portal site starts without a problem.
