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 network problem.

Hello experts

Windows 2000 AD network
all HP /  XP desktops (Mostly Intel 1000 nics)
Some Sun servers, HP, compaq

We have a lan with 15 servers,  and est 500 desktops. all the network is running really slowly (as far as im aware, it always has).  Traffic bandwidth reports show that daily bandwidth is an average of 6mbps on the core of the network (Layer 3 Netgear switch)  so that thing is crawing, and doing no work.

Copying a 700mb ISO file using windows I get a transfer rate 2mbps (41 minutes)

Heres the interesting bit:
Copy the same file on the same machine under kubuntu I get Transfer of 63mbps (72 seconds)

Under windows I use netCPS bandwidth analyser. it transfers a gig of data in under 2 minutes. 92mbps.
I get the same pattern where ever I try this on the network. (I've tried from different switches, different servers, different desktops ) all the same.

Any ideas?
