I think the problem is that you are hosting on a Windows Server .
You need to be a little more specific when you say the site constantly goes down. Do you mean the server is not reachable at all (for example, can you ping it when it fails), or is it only HTTP that fails? What type of site is it, is it database, ASP, ColdFusion intensive? How much traffic does the site generate, is it particularly busy? What do you have to do to make the site reachable again?
Answers to these questions my help narrow down the focus..
yeh windows is awful no the server is not reachable until I hard reboot it, and then it goes down again usually within 1-2 days. I can't ping it, you can check it for yourself also it is alfamovie.com 18.104.22.168. It is file download for movie site, so is should be database and badnwdith intesive it doesn't use cold fusion
I assume since it is movie site, you are talking about large files? Have you talked to Microsoft at all about optimizing the Windows 2000 TCP stack? You may want to do that to see if you can improve the number of simultaneous TCP connection it can run.
Do you have remote access to the server? If so, check a couple of things:
1. from a command line run netstat -an to see if there are excessive amounts of open connections. If there are connections that are left open (in tcp_wait) this might cause a buffer overflow in the TCP stack and it would knock the server offline.
2. Check the even viewer to see if there are any events that seem to be triggered around the same time as the server becomes unresponsive.
Finally, you may want to run performance monitor for a couple of days - and log the data. This will help you narrow down from where the problem is originating.
Alternatively...you could wait for Mike, from RackMY, to find this thread...and he will undoubtedly have a better answer .
