500 Internal Server error on Phone Provisioning V14

[allteks]

Hi,

Just upgraded from 12.5 to 14 and I now get a "500 Internal Server Error" when I go to the Phone Provisioning Tab. All worked fine in 12.5.

Paths and URL's all look correct. Folders exist on the servers etc. Any idea how to resolve?

Thanks

Hi there,
I believe the issue is that through your windows features the ASP.NET is not installed, can you verify and install if missing, then restart services and web server?

Had this same message and can confirm installing ASP.NET in windows features fixed the issue.
