HTTP Error 405 on POST

Hello all,

I'm having a problem with IIS wherein it returns an error 405 (Resource not
allowed). I'm afraid I'm rather short on specifics at the moment because a)
I don't know IIS, and b) the web pages in question were written by another
group within the company. I'm just the one who's supposed to install it and
get it working.

Here's what I know: The system is Windows 2000 Server SP4, with all the
latest updates, running IIS 5.0. There is a line in the IIS log as follows:

2005-11-14 18:43:07 127.0.0.1 - 127.0.0.1 80 POST /gemreports/ - 405
Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.0;+.NET+CLR+2.0.50727)

So it appears that the HTML is trying to POST something, and IIS objects.

We have this same HTML running successfully on a larger system using Windows
2003 Server SP1, running IIS 6.0 and also ISA server. We had some
configuration problems on that computer, but they were mostly related to
getting ISA server set up; we didn't see the 405 error at all. I have
compared the settings of the two IIS servers, and although there are some
differences due to the versions they seem equivalent.

I've read numerous articles all over the web about error 405. Most don't
suggest any specific fix, and the ones that do didn't fix my problem.

If you have any suggestions of things to look for, or settings to check, I'm
all ears. If there is other information you need in order to narrow this
down, just let me know how to get it and I'll look it up.

Thanks for any assistance.
