IIS stops responding, but no log errors

[SloppyGoat]

Ok, I'm about to throw my server right out the #&^$R%* window!
Here's the deal:
I'm running a vBB on W2K Server/IIS/PHP4.12/MYSQL/gzip compression.
Everything works fine, most of the time. But lately I have this strange problem. Suddenly, my site goes down and you get page not found. So, I switch over to my server to check the events, and no errors. And everything appears to be fine. IIS says it's running and everything. The only way you can even tell that something is wrong, is that it's not working!
So, I tried stopping/restarting IIS, and it gives me an "address already in use" error.
Checking the ports, nothing is using 80 except inetinfo. Also, W2K doesn't seem to want to shutdown after this happens.
If I reboot, it comes back up and acts as if nothing ever happened....until the next time it happens. :(

I have had a few errors in the past, but never when this is happening. This is one of them.

Event id: 115
W3SVC could not bind to instance 1

I've looked this up, and the information on it doesn't seem to pertain to my problem here. It said to delete the SSL port, but you can't. Buttons are grey in that field.

I cleared the event log so I wouldn't get confused. I don't have the exact errors. I will save them if I ever see them again.

Anyway, can anyone here suggest anything to check? I'm stumped on this one. It seems there are just no clues as to what's happening. :(

Try disabling your screen saver and see if that helps.

I had a similar problem with IIS and CGI. When ever the screen saver kicked on, my CGI processing got kicked off.

Welcome to WebmasterWorld SG! :)

I'm far from a server expert but, if you haven't done so already, you should probably apply all of the latest updates to W2K and IIS. Pay particular attention to the security oriented fixes. There are still many IIS servers infected with the Nimda virus and you may be getting visited by one or more of them. They could be crashing your server while trying to infect it.

Also, if no one here can provide a solution for you, there's a very active IIS forum here [winnetmag.com] that may be of help. Just don't forget to stop back and see us! ;)
