MOSS Access Denied – BackConnectionHostName or DisableLoopBackCheck

When attempting to view a MOSS (SharePoint) 2007 or SharePoint 2010 site locally from a Web Front End (WFE) you get an error stating:

"HTTP Error 401.1 – Unauthorized: Access is denied due to invalid credentials."

I have noticed that this happens on Windows 2003/2008 Server SP1/SP2/R2 when using Host Headers and Alternate Access Mappings on a web application in MOSS 2007. If you can access the site from remote machines and cannot access the site from the server itself, then this might be your issue.

These below registry settings needs to be handled while we are trying to access with Host Header and AAM. We need to keep it handy .

If you cannot access the web site locally or remotely from other machines then there is an issue with security on the site and/or possibly a Kerberos related security issue

There are two Method to resolve this issue.

Method 1: Specify host names

To specify the host names that are mapped to the loopback address and can connect to Web sites on your computer, follow these steps:

1. Click Start, click Run, type regedit, and then click OK.
2. In Registry Editor, locate and then click the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Lsa\MSV1_0

3. Right-click MSV1_0, point to New, and then click Multi-String Value.
4. Type BackConnectionHostNames, and then press ENTER.
5. Right-click BackConnectionHostNames, and then click Modify.
6. In the Value data box, type the host name or the host names for the sites that are on the local computer, and then click OK.
7. Quit Registry Editor, and then restart the IISAdmin service.


Method 2: Disable the loopback check

Follow these steps:

1. Click Start, click Run, type regedit, and then click OK.
2. In Registry Editor, locate and then click the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Lsa
3. Right-click Lsa, point to New, and then click DWORD Value.
4. Type DisableLoopbackCheck, and then press ENTER.
5. Right-click DisableLoopbackCheck, and then click Modify.
6. In the Value data box, type 1, and then click OK.
7. Quit Registry Editor, and then restart your computer

 

 

If you have a more elegant solution/suggestion – please post a comment… I'll be happy to hear.

Customize Search Results in SharePoint 2010 – only show documents in search result.

After configuring the Search Service Application and completion of the crawl, now it was the time for search results. My requirement was to show only documents in the search result. The option were

1.     Configure the search scope

2.     Remove file types – from crawl

3.     Customize the search core result webpart.

I took the last option since I am using a custom branding for my site and I cannot let the user to navigate to the out of the box pages.

The steps are very easy, except the xslt modification. I modified the xslt for the search result webpart from the help from the sites mentioned in reference section. Combining and putting some custom logic I could achieve the solution.

My xslt shows the result in a tabular view and only documents such as doc, docx, ppt.. etc.

The magic xslt is below:

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" exclude-result-prefixes="xsl msxsl ddwrt" xmlns:ddwrt="http://schemas.microsoft.com/WebParts/v2/DataView/runtime" xmlns:asp="http://schemas.microsoft.com/ASPNET/20" xmlns:__designer="http://schemas.microsoft.com/WebParts/v2/DataView/designer" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:SharePoint="Microsoft.SharePoint.WebControls" xmlns:ddwrt2="urn:frontpage:internal">   <xsl:output method="html" indent="no"/>   <xsl:param name="dvt_adhocmode">sort</xsl:param>   <xsl:decimal-format NaN=""/>     <xsl:param name="FileName" />   <xsl:param name="dvt_apos">'</xsl:param>   <xsl:param name="dvt_fieldsort" />   <xsl:param name="dvt_filterfield" />   <xsl:param name="dvt_sortdir">ascending</xsl:param>   <xsl:param name="dvt_sortfield" />   <xsl:param name="dvt_sorttype">text</xsl:param>   <xsl:param name="dvt_filterfields" />   <xsl:param name="dvt_partguid" />     <xsl:param name="AlertMeLink" />   <xsl:param name="AlertMeText" />   <xsl:param name="ShowMessage" />   <xsl:param name="ShowActionLinks" />   <xsl:param name="SrchRSSText" />   <xsl:param name="SrchRSSLink" />   <xsl:param name="SearchProviderText" />   <xsl:param name="SearchProviderLink" />   <xsl:param name="SearchProviderAlt"/>     <xsl:param name="ResultsNotFound" />   <xsl:param name="NoResultsSuggestion" />   <xsl:param name="NoResultsSuggestion1" />   <xsl:param name="NoResultsSuggestion2" />   <xsl:param name="NoResultsSuggestion3" />   <xsl:param name="NoResultsSuggestion4" />   <xsl:param name="NoResultsSuggestion5" />   <xsl:param name="AdditionalResources" />   <xsl:param name="AdditionalResources1" />   <xsl:param name="AdditionalResources2" />   <xsl:param name="IsSearchServer" />   <xsl:param name="Period" />   <xsl:param name="SearchHelp" />   <xsl:param name="Tags" />   <xsl:param name="Keyword" />       <xsl:variable name="dvt_1_automode">0</xsl:variable> <!-- XSL transformation starts here -->   <xsl:template match="/">     <xsl:choose>       <xsl:when test="$ShowMessage = 'True'">         <xsl:call-template name="dvt_1.empty" />       </xsl:when>       <xsl:otherwise>         <xsl:call-template name="dvt_1"/>         <style type="text/css">           .ms-alternatingstrong           {           background-color:#e3efff;

The output looks like below:

 

There are lot of places could further be modified as per your requirements. I have kept the xslt with comments for easy understanding. Don’t ask me each and every line, I am not a master in xslt though. I am sure this will help a lot of people struggling with modifying search result.

 

Thanks for reading…

 

If you have a more elegant solution/suggestion – please post a comment… I’ll be happy to hear.
