PHP stopped working (possible inetpub folder problem?)

This is a long shot, but... I'm running PHP5.2.5 on Win2000 with IIS 5.0. PHP was working fine until yesterday -- when I might have accidentally moved some files around in the inetpub folder (b/c of a super-sensitive touchpad on my laptop :< I wasn't swift enough to hit "undo" after that happened. Now, when I try to open PHP files in Internet Explorer, I just see the PHP code. I don't think I've messed up IIS -- it seems to be running fine -- and I don't think I messed up the PHP525 or WINNT folders. I'm guessing this problem might be because of the folders I possibly moved in inetpub --- but maybe there's another reason that I'm not seeing? Any ideas? Does anyone know how the inetpub folder is *supposed* to be organized? Here's my current directory structure: -Inetpub |-AdminScripts |-ftproot |-iissamples |-homepage |-themes |-sdk |-admin |-asp |-applications |-components |-database |-docs |-interaction |-simple |-transactional |-mailroot |-Scripts |-webpub |-wwwroot |-php_files If this structure is messed up, can you tell me how I should move the folders to get PHP working again? Alternatively, I'm thinking of just re-installing PHP, and if that doesn't work, and possibly reformatting my hard drive and reinstalling Win2000. Thanks in advance for any help!
