You do not have permission to view this directory or page using the credentials provided

The web site of the server suddenly looks like this. Inexplicably suddenly this is the case. View the IUSR anonymous account, found it belongs to the Guests group, the site also allows anonymous access. No problem. Picture

The server happens to have a virus that is caused by the virus. Then try to change the partition, or not. It is important to try the following methods:
Create an account number that belongs to the Guests group. In IIS, replace the anonymous account in the Web site with a new anonymous account. Everything OK ...
The default anonymous account password how has been modified ... The server found a lot of anonymous accounts, is not a PHTP site to an anonymous account ... Depressed...

When you configure IIS, you should do a little better if you are safe. There will be all kinds of problems. For example, the common access to the Web page will pop-up user name password login interface, or access to some kind of page such as html,asp nothing, but access to JSP or PHP has problems, show 401.3 ACL prohibit access to resources and other common solution is.

1, error number 401.1
Symptom (s): HTTP error 401.1-Unauthorized: Access denied due to invalid credentials.
Analysis:
Because the user is using anonymous access to the account (the default is the IUSR_ machine name) is disabled, or does not have access to the computer, will cause users inaccessible.
Solution:
(1) To see if the anonymous account for site security settings in IIS Manager is disabled, and if so, try to enable it in the following ways:
Control Panel-> Management tools-> Computer Management-> Local Users and groups, enable IUSR_ machine name account. If it is not resolved, proceed to the next step.
(2) View the default anonymous access account for the site in IIS Manager or the group to which it belongs, in the local security policy, if there is no attempt to grant permissions with the following steps:
Start-> program-> Administrative Tools-> Local Security Policy-> security Policy-> Local policy-> User rights Assignment, double-click "Access this computer from the network" to add the IIS default user or the group to which it belongs.
Note: The general custom IIS default anonymous access account belongs to the group, and for security, there are no special needs, please follow this rule.

2, error number 401.2
Symptom (s): HTTP error 401.2-Unauthorized: Access was denied due to server configuration.
Reason: Anonymous authentication was turned off
Solution:
Run inetmgr, open the Site Properties-> Directory Security-> authentication and access control-> Select Enable Anonymous access, enter a username, or click "Browse" to select a legitimate user, and then confirm the password two times.

3, error number: 401.3
Symptom (s): HTTP error 401.3-Unauthorized: Access because the ACL is denied to the requested resource's settings.
Reason: IIS anonymous users generally belong to the Guests group, and we generally put the site's hard drive to the Administrators group, at this time, in accordance with the principle of inheritance, the site folder only members of the Administrators group can access, Insufficient NTFS permissions to access the file by IIS anonymous users, causing the page to be inaccessible.
Solution:
Permission to access a Web site folder to an IIS anonymous user by entering the security options for the folder, adding IIS anonymous users, and giving them the appropriate permissions, generally read and write.

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 mistakes, made this summary, I hope to help you:
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.

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
Digest authentication overcomes many of the drawbacks of basic authentication. When Digest authentication is used, the password is not sent in clear text. In addition, you can use Digest authentication through a proxy server. Digest authentication uses a challenge/response mechanism (the mechanism that is used to integrate Windows authentication), where passwords are sent in encrypted form.
. NET Passport Authentication
Microsoft. NET Passport is a user authentication service that allows single check-in security to make it more secure for users to access the. NET Passport-enabled WEB sites and services. A. NET Passport-enabled site authenticates users based on the *. NET Passport central server. However, the hub server does not authorize or deny specific users access to each of the. NET Passport-enabled sites.
Workaround:
Configure different identity authentication (typically anonymous authentication, which is the authentication method used by most sites) as needed. Authentication options are configured under IIS Properties-> Security-> authentication and access control.

Problem 4:IP Limited improperly configured
Examples of symptoms:
HTTP Error 403.6-Prohibit access: The IP address of the client is denied.
Reason Analysis:
IIS provides a mechanism for IP restrictions that you can configure to restrict a ㊣p from accessing a site, or to restrict access to a site by only certain IP, and error prompts if the client is within the IP range that you are blocking, or not within the range you allow.
Workaround:
Access to IIS Properties-> security->ip address and domain name restrictions. If you want to restrict access to certain IP addresses, you need to select an authorized access point to add an IP address that is not allowed. Conversely, you can only allow access to certain IP addresses.

Problem 5:IUSR account is disabled
Examples of symptoms:
HTTP Error 401.1-Unauthorized: Access denied due to invalid credentials.
Reason Analysis:
Because the user is using anonymous access account is the IUSR_ machine name, so if this account is disabled, will cause users inaccessible.
Solution:
Control Panel-> Management tools-> Computer Management-> Local Users and groups, enable IUSR_ machine name account.

Problem 6:ntfs permissions set improperly
Examples of symptoms:
HTTP Error 401.3-Unauthorized: Access because the ACL's settings for the requested resource were denied.
Reason Analysis:
Users of a Web client are subordinate to the user group, so if the file has insufficient NTFS permissions, such as no Read permissions, it will cause the page to be inaccessible.
Solution:
Enter the Security tab of the folder, configure user permissions, or at least Read permissions. About NTFS permission settings are no longer fed here.

Problem 7:iwam account is not synchronized
Examples of symptoms:
HTTP 500-Internal server error
Reason Analysis:
The IWAM account is a built-in account that the system automatically builds when IIS is installed. IWAM account is established by active Directory, IIS metabase database and COM + application tripartite use, the account password is saved by three parties, and the operating system is responsible for the three-party saved IWAM Password synchronization work. The system to IWAM account password synchronization work sometimes ineffective, resulting in IWAM account password is not uniform.
Solution:
If there is an ad, select Start-> program-> Administration Tools->active directory Users and Computers. Set the password for the IWAM account.
Run c://inetpub//adminscripts>adsutil SET w3svc/wamuserpass + Password Sync IIS metabase database password
Run cscript c://inetpub//adminscripts//synciwam.vbs-v sync iwam account password in COM + applications

Problem 8:mime Setup problem causes some types of files to be downloaded (for example, ISO)
Examples of symptoms:
HTTP Error 404-file or directory not found.
Reason Analysis:
IIS6.0 has canceled support for some MIME types, such as ISO, causing client downloads to go awry.
Workaround:
The property->http header->mime type-> new in IIS. In the dialog box that follows, the extension is filled in. The Iso,mime type is application.

In addition, firewall blocking, ODBC configuration errors, Web server performance restrictions, thread restrictions, and other factors that cause the IIS server can not access the possible reasons, here is no longer one by one feed.



This happened to my site: Originally still can open, and then I use FTP to download the site to the local, and then login to the site will need to verify the user name and password, but enter the FTP username and password or not, has been let me input, the point of cancellation will appear below the situation, This is the server problem or my local IIS out of the problem ah. The need for expert answers help.

HTTP Error 401.3-access denied by resource ACL


4, the operation must use an updatable query

5, you are not authorized to view the page; you are attempting to access a WEB server that is not allowed to access

A list of IP addresses for this web site, and the IP address of the computer you use to browse

Reason:

This is a user rights issue because the disk you are using is in NTFS format.

Workaround:

First, add users ("Everyone" or "IUSR_ Your machine name", such as Iusr_hong, "Internet Guest user")

Second, modify the user rights (to read, write, modify, or even full control of the permissions, according to your own needs, you can try)

Detailed steps:

First step:

Open a D disk at random--click the top menu bar "Tools"--"Folder Options"--"view"--find "Use Simple File Sharing (recommended)" In the Advanced settings to remove the front hook.

Step Two: Add Users

Right-click the folder where you use IIS to publish your site--"Properties"--"security"--"Add" button to add users--"advanced"--"Find Now"--check "Everyone" or "IUSR_ Your machine name"--OK

Step Three: Modify user rights

Select the user you just added ("Everyone" or "Internet Guest user")--"Full Control" in the permission settings before the hook--OK

(Note: In the list of allowed before the hook, if you are afraid of trouble, you can directly give it "Full Control permission", or according to your needs, to read and run, write, modify and other permissions, you can try it yourself)

General to this step on it, if there is a problem, then proceed to the following steps.

IIS, Directory security, "Anonymous access" before the hook, there will be the default "IUSR_ your computer name" This user and the default password.

(1, if "username" there is no default "IUSR_ your computer name" This user, then click "Browse", "Advanced", "Find Now", select "IUSR_ Your machine name", OK, OK;

2, if there is no default password, then "Allow IIS to control password" before the hook)

OK, or take this step again:

First, the home directory, "Execute permissions" select "Pure Script";

Second, home directory, configuration, Options, "Enable parent path" before the hook.
