HTTP 401.1 - Unauthorized: Logon Failed Internet Information Services - IIS

[Neel21]

Hi,

I downloaded the ISS 5.1 and create a local server, however when trying to access it I get the following error message :

HTTP 401.1 - Unauthorized: Logon failure
Internet Information Services

I have WinXP Pro SP2 I have tried various solutions through Google, which spoke of a problem with the loopback feature SP2s safeguards. I am not particularly technically savvy, working my way through the books today. If anyone can help me I would appreciate it !!!

HTTP 401.1 - Unauthorized: Logon failure is due to IIS anonymous user has probably been removed, either accidentally or password has changed.

Try to open IIS Manager (Start-> Run-> '-inetmgr'> OK), right-click the Default Web Site, choose Properties, select "Directory Security", click 'Edit' button next to "Anonymous Access" (the checkbox should be checked), and now enter your username and password in the credentials.

To resolve your Logon failure issue , try the following steps :

1. Go to Control Panel -> Administrative Tools -> Internet Information Services
2. Next, select Local comupter "Web Site" -> "Default Web Site"
3. Then click on the directory containing your site or if you are in the rool, click the folder with the "right Default Web Site".
4. Then under the "directory security" tab click the "Edit" under "anonymous access and authentication control".
5. Uncheck "Integrated Windows authentication" and then check "anonymous access " on top. Be sure to check "Allow the ISS .... control"

Now you go and try new website. It should work.

Unauthorized: Logon Failed error, because SQL Server Reporting Services needs to use integrated security and not VS2008 deploy reports when anonymous authentication is turned on. So make sure you have the correct name of the IUSR account specified in the IIS MMC, and also has the correct password. You may have to disable the password box control and manually provide one - which also means you have to change the User Manager to match.
