Access to ctldl.windowsupdate.com when using Bing maps control RRS feed

  • Question

  • We are using bing map controls and map data on a Windows Mobile device. The device is in use in a enterprise environment and access to internet is blocked except for a few whitelisted URLs.

    We see that the device is trying to access "ctldl.dowindowsupdate.com" when we launch the map control and since that URL is not allowed from our network it results in blue screen and no map. Why is the device trying to go to that URL?

    If we allow access to that URL, would it also result in other MS apps and components to be updated? We don't want to update any other OS components or apps.

  • That's not a URL used by the map control - that looks like a general Windows update URL. Blocking that should have no impact on the map control operation (but will prevent the device from getting critical security updates).

    You're probably blocking other URLs that result in map data not being downloaded. Map data is downloaded by a system service using the same networking stack that Windows update uses (to download offline map data updates without impacting user networking). If you're blocking Windows update, that would probably also block map data.

    Have you tried downloading map data for offline use? You can do that once on the device in a connected state and then you won't need to download it when out in the field.
