Hello darylm,
I understand you are not getting internet access on the phone when using Intel® My WiFi Dashboard as a hotspot.
If Intel® My WiFi Dashboard allows you to enable WiFi Direct and Hotspot I believe it is working properly; or at least it is not installed as Lite version but as Full version. The software versions should work together.
I was able to confirm that by stopping the ICS service the internet connection stops to my phone; but it was still connected locally, no visible changes from Intel® My WiFi Dashboard as the options remain on. As soon as I restart the service the internet connection resumes.
Please check the following in Intel® My WiFi Dashboard: You may open the Help window by clicking on the “?” button. Go to the search tab, type “ICS” and open the only result you will find, which shows some information for “Unable to Activate Internet Connection Sharing”.
I also wonder what would happen if you try connecting to a different network. It is possible the issue is coming from the hotel connection somehow since only one device connects at a given time or from Windows* (services), not necessarily a group policy.
It is an issue difficult to troubleshoot; however I hope these findings will give you an idea or a possible solution.
