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!

MS FTP server not allowing login connections

Tags: ftp
FTP Login problem. IE70 not displaying login prompt. Using IIS 60 with FTP services.
When set for anonymous login it works both local (behind firewall and on the domain) and remote. Tested with Ws Ftp Pro program, IE70, and Firefox. When set to require login, local works for all programs. Remote works for Ws Ftp Pro but not for IE70 or Firefox. Browsers never display login prompt. They have been working up til a few weeks ago. No updates or changes on server. I have uninstalled FTP and reinstalled. Checked and reset permissions. Local use of browsers displays the login prompt and connects fine.

The log (following) seems to show multiple user connection attempts (331) for the successful browser connection ([159] through [163]) although this was not evident from the browser. The failed browser attempts only indicate one user connection attempt. To get more confusing I found a Win2000 server with IE60 that was successful remotely (log at end) and it shows the multiple login attempts also. I also tested a Win 2003 server remotely with IE60 that was not successful.


IE 70 BROWSER MESSAGE ON FAILURE
Technical Information (for support personnel)
    * Error Code: 502 Proxy Error. The login request was denied.
The logon account might have been disabled or logon information might
have changed. Log on again to verify that the information was typed
correctly. If the problem continues, report the problem to the administrator
of the Internet server you are requesting. (12015)
