How to stop IIS asking authentication for default website on localhost

Question

I have IIS 5 1 installed on Windows XP Pro SP2  Besides I have installed VS 2008 Express with  NET 3 5  So obviously IIS is configured for ASP NET automatically for  NET 3 5  The problem is whenever I access http   localhost IE  amp  Firefox both presents authentication box  Even if I enter Administrator user and its password  the authentication fails  I have already checked the anonymous user access  with IUSR  user and password is controlled by IIS  in Directory Security options of default website   However other deployed web apps work fine  does not ask for any authentication    In IE this authentication process stops if I add http   localhost in Intranet sites option   Please note that the file system is FAT32 when IIS is installed   Regards  Jatan

It could be because of couple of Browser settings. Try with these options checked..

Tools > Internet Options > Advanced > Enable Integrated Windows Authentication (works with Integrated Windows Authentication set on IIS)

Tools > Internet Options> Security > Local Intranet > Custom Level > Automatic Logon

Worst case, try adding localhost to the Trusted sites.

If you are in a network, you can also try debugging by getting a network trace. Could be because of some proxy trying to authenticate.

IIS uses Integrated Authentication and by default IE has the ability to use your windows user account   but don t worry  so does Firefox but you ll have to make a quick configuration change   1  Open up Firefox and type in about config as the url  2  In the Filter Type in ntlm  3  Double click  network automatic-ntlm-auth trusted-uris  and type in localhost and hit enter  4  Write Thank You To Blogger  As Always  Hope this helped you out   This was copied from link text

What worked for me is      Click Start control panel Administrative Tools Internet Information Services  Expand the left tree  right-click your WebSite Properties  Click on Directory Security  then in  Anonymous access and authentication control  click on Edit  Enable Anonymous access browse  enter the credentials of the admin  like Administrator   check names    Click OK  Apply the settings and it should work fine

This is most likely a NT file permissions problem  IUSR  needs to have file system permissions to read whatever file you re requesting  like  inetpub wwwroot index htm  If you still have trouble  check the IIS logs  typically at  windows system32 logfiles W3SVC

It is easier to remove the  Default Web Site  and create a new one if you do not have any limitations   I did it and my problem solved
