Pick IIS 6 Frequently Asked questions

Many friends have encountered many problems when they use the IIS6 website. And some of these problems in the past IIS5 inside have encountered, and some are new, I worked on the afternoon, did a lot of experiments, combined with the previous experience of debugging, made this summary, I hope to give you a helping hand
Issue 1: Parent Path not enabled
Examples of symptoms:
Server.MapPath () error ' ASP 0175:80,004,005 '
The Path character is not allowed
/0709/dqyllhsub/news/opendatabase.asp, line 4
The character ' ... ' is not allowed in the Path parameter of MapPath.
Reason Analysis:
Many web pages use things like. /formatted statement (that is, the page that returns to the previous layer, which is the parent path), and IIS6.0 for security reasons, this option is turned off by default.
Workaround:
In IIS, the properties-> the home directory-> configuration-> option. Check the "Enable Parent path" front. Confirm the refresh.
Problem 2:asp Web extensions improperly configured (same applies to asp.net, CGI)
Examples of symptoms:
HTTP Error 404-file or directory not found.
Reason Analysis:
The new Web application extension option is added to IIS6.0, where you can allow or disallow ASP, ASP.net, CGI, and IDC programs, which are prohibited by default.
Workaround:
In the Web service extension in IIS, select Active Server Pages and click Allow.
Improper configuration of identity authentication
Issue 3: Improperly configured identity authentication
Examples of symptoms:
HTTP Error 401.2-Unauthorized: Access was denied due to server configuration.
Reason Analysis: IIS supports the following types of Web authentication methods:
Anonymous authentication
IIS creates a IUSR_ computer name account, where the computer name is the name of the server that is running IIS, and is used to authenticate anonymous users when they request Web content. This account grants the user local logon rights. You can reset anonymous user access to use any valid Windows account.
Basic Authentication
Use Basic authentication to restrict access to files on an NTFS-formatted WEB server. Using Basic authentication, the user must enter credentials and access is based on the user ID. Both the user ID and password are sent across the network in clear text.
Windows Integrated Authentication
Windows Integrated authentication is more secure than basic authentication and works well in the intranet environment where users have Windows domain accounts. In integrated Windows authentication, the browser attempts to use the credentials that the current user uses during the domain logon process and prompts the user for a user name and password if the attempt fails. If you use integrated Windows authentication, the user's password will not be transferred to the server. If the user logs on to the local computer as a domain user, he does not have to authenticate again when he accesses a network computer in this domain.
Digest Authentication
