Error: The Web Server Has Been Locked Down and Is Blocking the DEBUG Verb

To enable debugging on a Web server with URLScan installed

Locate the Urlscan.ini file. Normally, you will find it in a directory that looks something like this:

C:"WINNT"System32"Inetsrv"urlscan

Create a copy of the file, and name it Urlscan.old.

Open the original copy of the Urlscan.ini file using Notepad or the text editor of your choice.

In Urlscan.ini, locate the [AllowVerbs] section. Add DEBUG to the [AllowVerbs] section. If you see ;DEBUG in the [AllowVerbs] section, remove the semicolon to uncomment the verb.

Locate the [DenyVerbs] section. If DEBUG appears in the [DenyVerbs] section, remove it.

Save the file.

Restart the server or restart IIS.
