Any IIS experts out there?

I'm just trying to get a feel if anyone here on TLF is quite familiar with IIS (Internet Information Services).

At work we run a server with Windows Server 2003. Lately we've been having some applications (written well before me) that are starting to hang up the server. The person that manages our server doesn't know much about trying to pin point which app (or apps) are causing the trouble.

I have some things I'm working on now, but plan on spending some time on Google later to figure this out. I just thought I'd see if maybe we had some members here with some ideas.

Thought I'd update anyone that finds themselves looking at this thread, some information that I found.

The first thing I did was download Process Explorer:

For those who haven't used it, it makes Task Manager look like a little boy compared to a body builder. Ok, that may be a bad reference, but Process Explorer is simply more powerful.

I used it to check out which Application Pools (each have it's own instance of w3wp.exe) were using up more juice. Anything from CPU/Memory/IO performance.

After identifying which process(es) were being naughty, I decided to run an IIS Debug Diagnostic Tool.

Following some simple steps here: http://serverfault.com/questions/163561/...865#166865
I was able to effectively check out which exceptions were present in the application. If the App was hung up, running a Full Dump would tell me where it was hung up, and what it was waiting for.

I then ran a FULL Dump of all the IIS processes and actually found out quite a bit more about he other pools that had seemed to be working fine.

If you are experienceing Deadlock, CPU Spiking, Poor Performance, Timeouts... I'd check into the links I mentioned here.

Good luck. :D
