Cannot access a SharePoint site collection I created using host header, but others can log into it. RRS feed

  • Question

  • I have created a web application and site collection in SharePoint using a host header for others to access (acme.company.com for example).  I have created it, set up the host header to point to this site, reset IIS and pinged the site for it to work.  I have about 4 people who can all access it just fine, and do not have to log in since the site recognizes their credentials with it being an Intranet site.  However, I am the only one who can not access it as it shows me a log in box...I enter my credentials correctly but it keeps popping back up 3 times, and eventually takes me to a screen saying I cannot access the site.

    I am guessing it could be a loopback problem,  meaning that I am hitting my own IIS via "127.0.0.1" or "localhost".  I checked and the host header should be ok, and there's nothing wrong with my setup since others can get in.  I have no clue what is going on and where to look since I've tried several things to no avail.   This is a big problem obviously because I need to set up some additional things that others cannot do, but I cannot access my own site.

    Any idea and suggestions as to where to look?  I greatly appreciate the help!

  • First thing is to try a different browser like Safari for Windows (or Firefox or Chrome).

    When I was writing my book I sometimes found that I needed to access my test site via Safari once and then I could access via IE.

    I'm not saying this is the solution just that it will help you to exclude things if Safari works and IE doesn't.

  • Hi easyeman77,

    Did you install Microsoft Windows XP SP2 or Microsoft Windows Server 2003 SP1? These two service packs include a loopback check security feature that is designed to help prevent reflection attacks on your computer. If you use integrated authentication and has a name that is mapped to the local loopback address, this issue will occur. And if you browse the web site from a client computer, the site works as expected.

    Please try to access the site on another computer with your account. If you can access it successfully, please configure your server follow this KB. http://support.microsoft.com/kb/896861. If not, please check your permission on the site.
