The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Asked by nbctcp in Remote Desktop/Terminal Services, Windows Server 2008

Tags: , ,

PROBLEM:
-everytime trying to connect win2k8x64ts1 using RDP 6.1 through TS Gateway, it failed to connect with error message "Terminal Services connection authorization policy (TS CAP) is preventing connection to the remote computer through TS GAteway ..."
-in TS Gateway Event Viewer-Windows Logs-Security

  ProxyPolicyName NAP TS Gateway
  NetworkPolicyName NAP TS Gateway Non NAP-Capable
  AuthenticationProvider Windows  
  AuthenticationServer win2k8x64tsgw.test.local
  AuthenticationType Unauthenticated

So basically TS Gateway always think VistaSP1 is not NAP Capable.
Client is member of domain and in the same subnet as server.
How to fix the problem?

thanks
