HTTP 500 -- I've tried the usual stuff

Hey, guys. First post here on the ASP forums, but I moderate a couple car-related ones myself. I hope you can help.

I'm putting up some known-good asp code on an existing Win2k Pro box acting as a web server. I've ensured that proper permissions are on the folders, that it's as a subdirectory of the web-root, scripting is active, etc.

After performing a search on 500 errors here on the board, I also tried following some of the advice Doug and others provided. Disabled all firewall and anti-virus software without any changes. Also disabled "friendly" errors in IE. This is the result of that same 500 error without the friendly language:

Server Application Error
The server has encountered an error while loading an application during the processing of your request. Please refer to the event log for more detail information. Please contact the server administrator for assistance.

The web server log for the operation is pretty cryptic -- the standard time/IP/Operation/File/Error Number fair. It's just

22:34:46 208.180.133.241 GET /czl/testcode.asp 500

I'm at a bit of a loss. Is there an option I can set to get more detailed web-logging to offer more clues? Or does anyone have an idea on why this would be happening?

I appreciate your help.

Edit: IIS is undoubtedly loaded on the machine, but I'm not sure how to check which version. Can someone aim me in the right direction on that as well?

You install IIS on W2K from the control panel - add-remove programs - add-remove windows components. It will be IIS5.0 on W2K.

What does the event log say, are there errors logged there that would be a clue? Look in control panel - administrative tools - event viewer.

Ok, two things get triggered in the event viewer when I try to access an asp page.

The first is a warning.

"The server failed to load application '/LM/W3SVC/1/ROOT/czl'. The error was 'The server process could not be started because the configured identity is incorrect. Check the username and password.'.

Second is an error that reads:

DCOM got error "overlapped I/O operation is in progress. " and was unable to logon. \IWAM_DHFJGM11 in order to run the server: {3d14228D-FBE1-11D0-995D-00C04FD919C1}

I had already added the IUSR account priveleges to all relevant folders. It almost looks like I need to try adding IWAM (whatever that is?).

Just added IWAM to all the relevant folders. No change.

You might look around at www.iisfaq.com there is lots of good IIS stuff there.

Hey guys, this one had me stumped for a while. Here's the MS KB article that must be followed to the letter.
I used the 1st method and it solved my problems. Don't forget to call the synciwam.vbs script to reset the IWAM credentials for out-of-process MTS packages.

here's that link: http://support.microsoft.com/?kbid=297989

Hey, guys. Sorry for not posting in with the solution earlier.

For us, it appeared to be a corrupt install of IIS. Removing it and reinstalling it got everything working without issue.

Your mileage may vary.
