IIS stopped working on XP after installing EasyPHP / Apache

Hi all,

I have a huge problem with my IIS, which stopped working following an installation of an Apache server on my XP-based PC.

The history goes as follows:

1) I decided to experiment with PHP and such decided upon installing EasyPHP on my XP-based PC. Before the installation, my IIS was running perfectly, crunching my asp-pages as it's supposed to and localhost, localstart etc. were reachable as normal.

2) Following the installation of EasyPHP (at least my best guess is that this is in fact the root of my IIS problem?!), I could reach localhost no more, and when I tried running localstart.asp, I recieved a cryptic error message, informing me that the 'Object factory' could not create an object of some class?! If IIS was stopped and EasyPHP started localhost worked again, but of course this time in 'EasyPHP-mode' (and unable to interpret ASP scripts...)

3) Desperate as I was, I removed EasyPHP and re-installed IIS. Localhost was still not reachable, though, but now I only get a 'normal' 'Internal server error - the page cannot be displayed' error.

I searched everywhere via Google, but have not yet found an explanation, that can help me getting IIS back up and running.

Does anyone have an idea that might solve my problem? It would be extremely appreciated, thanks : )

Best regards and thx in advance,

You can't run two webservers on the same http port (port 80), that was probably the original cause of your problems. However if IIS isn't coming back to life after uninstalling Apache I guess something else got messed up.

You could try reinstalling IIS, perhaps. There is some ms command line program that resets IIS registry settings but I don't recall it's name.

Thank you - I searched Google and found that with the command 'iisreset', IIS values are reset. I tried that but now I'm back to this error message (translated from Danish, so might not be exact wording):

Error type: (0x80040111) Class factory cannot assign the requested class
/localstart.asp, line 46

Does that clarify anything?

Not for me, unfortunately. Try searching google for the error type code or some of the text from the error message is the best I can offer.

Well - thanks anyway. I guess I'll have to re-install XP : (

Next time - how do I go about installing a PHP capable webserver without destroying IIS settings?

Many people have successfully installed Apache on an IIS box. I have some NET webserver installed, it just runs on a different port. You might keep searching before reinstalling, there is probably some simple setting that needs to be changed. If you haven't take a look at www.iisfaq.com

I had the same problem; IIS was working fine until I installed Apache, PHP5 and MySQL. Interestingly enough, while I can't bring up localhost, I can still get the pages to show up when I point a different computer on my home network at the computer with IIS...
