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!

Impersonating user security context from NT AUTHORITY\NetworkService

Asked by kkamm in Windows Network Security, Miscellaneous Security, Networking Security Vulnerabilities

Tags: , ,

I have a system service which needs to make SQL queries to a server on our domain. This service also needs to write to a local event log, as well as update the local registry. I need an account for this service that is appropriate for a system service, but also allows it access to the functions mentioned above.

The NT AUTHORITY\NetworkService account has been suggested for a typical network aware service, but I get errors when attempting any local operations.

What I was considering is running the service under the  NT AUTHORITY\NetworkService account but temporarily running in a standard user context via impersonation to do any local operations.

My question is:
How much safer is it to temporarily run in a more privileged context from a less privileged one using impersonation?  What is the functional difference between running in the more privileged context from the start as opposed to impersonating  a more privileged  context from a less privileged one?Start Free Trial
