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.

yahoo, messenger, proxy

we had a new nokia IP 320 box with checkpoint NG with AI.

Our setup is:  LAN->Firewall->Router.
Our LAN consists of Exchange server and ISA server in caching only mode. STATIC NAT is configured for ISA server and exchange server. Rule configured in firewall for ISA server is to allow http,https,dns,yahoo messenger service. User's can access the internet through ISA server.no issues with internet access and e-mail flow.

we want users to use yahoo messenger with "use proxy" settings with ISA servername as the proxy server and port 8080. but it is  not working with this settings.
if i bypass the proxy server and access the firewall directly i can login to yahoo messenger i.e with rule defined on checkpoint firewall like my pc as source, any as destination and yahoo messenger as service. i can login with "no proxies" settings.  We dont want to use this settings.

We want all users to use our ISA caching only mode to be configured as proxy in yahoo messenger. I think there is something missing in the ISA server to forward the Request to Firewall.
NOTE: we have defined Allow protocol rule for any request on ISA server.

I Hope experts here can help me on this. what else needed to be configured on. its urgent..

Thanks
