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!

URGENT Massive unknown server activity (or attack?)

Asked by DLockwood in Windows Network Security

Tags: exchange

Go easy on me since I am a Web Programmer and not a Network or Server Engineer. :-)

I have a server running WIndows 2000 Server, IIS 5.0, Exchange 2000, SQL Server 2000, and Norton Corporate and Exchange Anti-virus. My Broadband connection goes through a Router that has basic blocking set-up but nothing specific. I only have 2 active e-mail addresses. I have 5 or 6 websites but they are mostly "Test" sites in which clients come and view progress on their Web Project. So, this server gets very little traffic.

I have been running this server for something like 2 years and never had a problem. Now, all of the sudden, starting yesterday morning, my server is working away. Hard Drive spinng and a constant noise. She is just working and working.

All of my internal apps and websites are very slow because the server is busy doing something else.

How do I find out what it is doing? Where do I even begin to look for a cause so that I can fix this. I have NO CLUE where to start.

Thanks in advance!
