I have a problem with gettnig attache/upload to work on our support system.

We're running a IIS6+PHP5+MySQL setup for Kayako's SupportSuite, and everything is running just fine, except the upload/attachment function. When trying to attach a file to a ticket-reply the browser just "thinks" for a while then display an "cannot display the webpage" type of error page. My guess is that the request times out, without anything being uploaded.

I have no experience with running PHP on IIS before, so I might have missed some vital configuration when setting it up.

Does anyone have a off-the-top-of-my-head idea of what could be wrong?

Permissions.

The IIS worker process that runs the PHP interpreter needs write access to the folder where it's going to save uploaded files.

IIS_WPG and Internet Guest Account have write permission on the folder. Is there any other process/user that need access? Shouldn't I get a "forbidden" error code if the process wasn't permitted to write? –  Marcus L Sep 2 '09 at 10:24

Which identity is the application pool configured to run as? If it's using the default, then it's NETWORK SERVICE; you should grant write access to that. –  Massimo Sep 2 '09 at 11:12
    
"Forbidden" is returned when the client can't do something; but in this case the client is simply requesting the execution of a script, it's the script itself that gets an error from the underlying O.S.; the most common result would be a 500 error, unless there's proper exception handling in the script. –  Massimo Sep 2 '09 at 11:14
    
You might be on to something with the application pool and NETWORK SERVICES. I'll give it a shot. –  Marcus L Sep 2 '09 at 13:03
    
I'll mark this as correct, but I ended up getting so tired of it that I switched to Apache instead... –  Marcus L Sep 3 '09 at 12:20
