Well this problem just started happening.

my inetinfo.exe just goes to 100% cpu usage for any http request.  I've tried resetting my computer, restarting IIS and reconfiguring pretty much every option i have.  I first noticed this problem after a hard reboot 2 nights ago, and I can't seem to fix it or find any relevant microsoft hotfixes.

when IIS is active all I have to do is request http://localhost/ and the thing locks up.  I can end task it, but the page is never generated and eventually IE times out.

has something been corrupted, and if so, how do i fix it?
has my configuration changed, and where was it changed?


im running IIS 5.1 (winXPpro w/ SP1)
not running SMTP server
not running FTP server
not running Web Printers
not running FrontPage Extentions

Does it spike or stay at 100% after the first request?

What happens if you leave it alone for a while, does it go down, produce an error?

Have you looked at the event viewer for any related problems?

it stays there.  even if i have the page from cache and i load a missing image the inetinfo just goes nuts and stays that way.
it never throws an error, and it doesnt go back to normal

the event viewer only logs my forced quits, nothing else...
example:
The World Wide Web Publishing service terminated unexpectedly.  It has done this 13 time(s).
The IIS Admin service terminated unexpectedly.  It has done this 13 time(s).

These are no forced stops or restarts

The World Wide Web Publishing service terminated unexpectedly.  It has done this 13 time(s).
The IIS Admin service terminated unexpectedly.  It has done this 13 time(s).

what else are you running on your machine? Anything like ColdFusion or ASP?

Do you knwo when this started happening? Right after something?

well, forced in that it wouldnt stop on its own and i had to "end-task" the thing.

i was running ASP, but i went back to just htm files and it does the same thing.
nothing but ASP and MySQL... which were working perfectly until recently

this started happening on December 8th, thats when the first hang ups started happening.  i remember i tried to run star wars jedi academy and my monitor turned off (ati drivers bug) and wouldnt come back on, so i had to hold the power button for 4 seconds to make my computer boot again.

LOL you are running games on a webserver ;-))

Hmm reinstall sounds like a good option..

Uninstall the game first is another option.
I wasn't really after a date but more like a specific event you can remember, like installing the game for example...

Turning the computer off the hard way might have corrupted something in IIS, the metabase maybe?
A reinstall is not to difficult, easily done...

this is my home computer... i use it for development as well

i really wasnt to avoid a complete reinstall of windows if at all possible.  if the metabase was corrupt, how would i go about replacing it?

You don't need a complete reinstallof your operating system, just IIS.


Go to control panel -> windows components -> internet information services remove it, and reinstall it it.

I tried that, but i encountered the same bug.

however, last night i was trying new things and turned off authentication for my NIC.
i then turned the Application Protection process pool from Low to Medium and suddenly eveything was back to normal.

When i turned NIC authentication back on... inetinfo did not go back to 100% cpu usage.  to this day i STILL cant duplicate the bug, but it must have had something to do with the Application Protection in IIS and some kind of authentication.

So I have a NEW question for 500 points  :)

My scripts don't use any Application, Cookie or Session objects, just an ADODB object, so how was the Application Protection affecting the performance of inetinfo.exe?

One of my questions was "Do you know when this started happening? Right after something?"

I reckon your answer should have been, yeah right after I enabled "Authentication on my NIC and changed some other settings"
Anyway, I'm out.......
Good luck..
