Windows 2003 ASP.NET Page Gives 404 File Not Found Error

with 36 comments

Today, one of my colleges shows me that I had the error which denies access to ASP.NET page (.aspx,.asmx,.asax) and shows 404 file not found.

I have tried 1 to 2 hour for just googling around for resolving this issue. But I could not think of keywords to search for. Then following steps resolved my problems. Thanks to GOD, GOOGLE and my MIND too 🙂

Basically first thing I did is put .txt and .asp file and test if it works for that extension. And It Worked !!!

Now next thing I did is go to the IIS log and see the entry of that request. It shows me something like

<Request data> …. 404 2 1260.

Now, From this, I googled and found out that this is 404.2 error and it is policy lockdown. Uhhh!! Found the problem.

Now, searched google about resolving this policy lockdown error. To resolve this. Goto IIS and expand the Main Server Node. Find the “Web Server Extension” directory and click on it. It shows list of extension to the right side. Please look at that amazing thing and somewhere your page is prohibited under that configuration. Please enable it and hurray!!! You are on your way.

  2. ARGH – I spent two days wondering… “WHY WONT IT SERVE THE DAMN PAGE???”

    Never though of looking there, a sys admin gave a VM with Win2003 and IIS configured, and told me to put the app on there.

    Runs like a champ now, thanks!

  3. OMG!!!! funny for me that was the first place I looked at but wasn’t paying attention. I was merely clicking on anything I could find hoping I find anything that has the word “ASP” but not “Active Server Pages”, why was it set to PROHIBITED damn!!!! One day it was working and then the next it stopped. Two weeks later I stumble into this page with google search string “IIS ASP file are not resolving”. I knew the IIS itself is not too blame as my PHP extension is working perfectly.

    Well anyways, you help me heaps. Thanks very much.

  10. Thanks for your tips!!

    I had it all working on IIS 5.0 (Windows 2000 Server) and used exactly the same configurations on IIS 6.0 (Windows 2003 Server), but just couldn’t have the included header/footer rendered! Finally came across your page from an answer of someone’s comment on a Forum through Google.

    Really helpful information, thanks again.

  25. Thanks. I had the same problem with asp files on a new W2003 installation. html was working but not the asp files.

    It’s IIS Manager/Web Service Extensions/Allow each relevant lines

  26. Same problem here. New Win 2003 install. I was certain I checked that 3 or 4 times… Sure enough, found this thead, went back and looked right at it. The ASP.NET extension was Prohibited. So, this one fixed my issue. Thanks!
