My website is hosted on a Windows server as part of a shared web hosting plan, the database is a Sql Server 2005.
The issue is that in the past few months I have noticed numerous occurrences of a "Service Unavailable" message on my website as well as occurrences where the page will load but the style sheet will not load.

When the "Service Unavailable" message occurs, if I refresh the page it will usually load after 1 or 2 times, sometimes with the style sheet and sometimes without out.

I have large site with many visitors. However I suspect that the load on the server is coming from the forum. It is a Snitz Forum and uses Classic ASP code. It is the only part of the website that I haven't built myself.

My basic question is, I need to know how many times per day, my site visitors are receiving this Service Unavailable message. and what I can do about it

How can I obtain this data? I don't think it is in the log files

Also any suggestions on how to lesson the load on the server would be appreciated. Do cookies cause a problem. I know the forum uses them extensively, as well as Application level variables and session variables.

So far the information I have Received from my hosting company is that my website continues to receive a very large amount of traffic, and is repeatedly hitting the 100 concurrent connection limit.

If someone attempts to connect to my website while there are already 100 active connections, the user will receive the service unavailable page. Basically 100 people can connect to mysite, but if 101 people try to connect that last person will get service unavailable.

Any help is much appreciated!
Thank You in advance.

Thanks for the info.

I will check it out more in depth tommorow.
One concern is I have is my website is on a shared hosting plan, I don't want to bring down the server.
Usually all topics posted are by folks with website hosted on their own server.
