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!

Slow https sites. Protocol SSL Tunnel - "Failed Connection Attempt"

Zones: MS Internet Security & Accel, Secure Socket Layer (SSL) & HTTPS, Enterprise Firewalls

Tags: Microsoft, Isa, 2004 SP3, 995 The I/O operation has been aborted because of either a thread exit or an application request.

My company is having lots of problems connecting to https sites. Lots of failed connection errors, resulting in really slow SSL sessions.

In the ISA 2004 logs I can see error msgs with :-
995 The I/O operation has been aborted because of either a thread exit or an application request.

I've tried increasing the connection limits to 200, installing sp3, checking dns settings, and reset the isa cache

A sample log is below.

The ISA box's roles are firewall//gateway whilst the web proxy (192.168.10.30) has Webmarshal installed and another server acts as the dns server

Any ideas?
