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!

My network is running very slow at certain times and not others (slow downs can last all day, or just 4 hours at a time). I am very new to diagnosing network problems, and my network is complex (at least to me). Please let me know where to start, which book to read or program to download, so I can get a picture of what is going on with the network find out how to fix it. Here is some basic information, if you need more, please let me know. Thanks, TJK.

Main Office:
5 servers - win 2003 stndrd edition on all. They are connected to 4 managed dell gigabit switches
2 servers have gig network cards, 3 others are 10/100
main building has cat5e running to the switches - about 50 users
2 cisco airnet wirless routers are also connected to the switches
dedicated T1 for internet going into instagate firewall, then into switch.

Processes servers are running:
terminal service, dns, active directory, exchange 2003 stndrd, print server, file server, symantec antivirus 11, symantec internet security, BES, domain controller, SQL, mysql, internal website, MAS accounting software written in provideX, roaming profiles, etc.

Remote Locations: (on same network, across the street)
3 remote locations connnected by cisco airnet 1400 wireless routers - about 25 users each remote location. remote location buildings running cat 5e.
10/100 main switches at remote locations, connected to the airnet router and user computers.

workstation notes:
all win xp pro sp2 - motherboard is similar to intel D915GUX with 10/100 NIC

Network notes:
I have a lot of generic (compaq\whatever brand) 5 port hubs to connect printers to the network in every location.
