    944267 How to troubleshoot common errors that occur when you run the SharePoint Products and Technologies Configuration Wizard on a computer that is running Windows SharePoint Services 3.0 or SharePoint Server 2007
  • Known issue 2
    
    Symptom
    
    Users are prompted for authentication when they try to browse a SharePoint site. Windows Server 2003 SP1 and Windows Server 2008 include a loopback check security feature that helps prevent reflection attacks on your computer. Therefore, authentication fails if the fully qualified domain name (FQDN) or the custom host header that you use does not match the local computer name.
    
    Workaround
    
    There are two methods to work around this issue. Use one of the following methods, as appropriate for your situation.
    
    Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
    322756 How to back up and restore the registry in Windows
    
    Method 1: Specify host names (the preferred method for NTLM authentication)
    
    To specify the host names that are mapped to the loopback address and can connect to websites on your computer, follow these steps:
    
    
    1. Set the DisableStrictNameChecking registry entry to 1. For more information about how to do this, click the following article number to view the article in the Microsoft Knowledge Base:
       
       281308 Connecting to SMB share on a Windows 2000-based computer or a Windows Server 2003-based computer may not work with an alias name
       
    2. Click Start, click Run, type regedit, and then click OK.
    3. In Registry Editor, locate and then click the following registry key:
       
       HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0
    4. Right-click MSV1_0, point to New, and then click Multi-String Value.
    5. Type BackConnectionHostNames, and then press ENTER.
    6. Right-click BackConnectionHostNames, and then click Modify.
    7. 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.
    8. Exit Registry Editor, and then restart the IISAdmin service.
    
    Method 2: Disable the loopback check (the less-recommended method)
    
    Warning This workaround may make a computer or a network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.
    
    The second method is to disable the loopback check by setting the DisableLoopbackCheck registry entry.
    
    To set the DisableLoopbackCheck registry key, follow these steps:
    
    
    1. Set the DisableStrictNameChecking registry entry to 1. For more information about how to do this, click the following article number to view the article in the Microsoft Knowledge Base:
       
       281308 Connecting to SMB share on a Windows 2000-based computer or a Windows Server 2003-based computer may not work with an alias name
       
    2. Click Start, click Run, type regedit, and then click OK.
    3. In Registry Editor, locate and then click the following registry key:
       
       HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
    4. Right-click Lsa, point to New, and then click DWORD Value.
    5. Type DisableLoopbackCheck, and then press ENTER.
    6. Right-click DisableLoopbackCheck, and then click Modify.
    7. In the Value data box, type 1, and then click OK.
    8. Exit Registry Editor, and then restart your computer.
