How to fix: Error accessing server locally by using its FQDN or CNAME alias

If you have been coming across an error while attempting to access the server locally via FQDN or its CNAME alias, you have come to the right place. According to our Support Team, we will experience one or more of the following symptoms in this scenario:

• “Access denied” error message
• Repeated logon windows
• “No network provider accepted the given network path” error message
• Event ID 537 in the Security event log

This error is a result of a new security feature in Windows Server 2003 SP1. This feature, loopback check functionality, is by default set to on in Windows Server 2003 SP1. Additionally, the DisableLoopbackCheck registry entry value is set to 0. We can find the loopback check functionality in the following registry subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\DisableLoopbackCheck.

Our Support Team has come up with two ways to resolve this issue:

• Create Local Security Authority host names that can be referenced in an NTLM authentication request
• Disable the authentication loopback check

How to create Local Security Authority host names that can be referenced in an NTLM authentication request

1. First, navigate to Start > Run, enter regedit, and click Ok.

   
2. Then, locate and select the following registry subkey:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0
3. Next, right-click MSV1_0 and point to New. Then click Multi-String Value.
4. After that, enter BackConnectionHostNames in the Name column and click Enter.
5. Then, right-click BackConnectionHostNames, and then select Modify.
6. Next, enter the CNAME or the DNS alias that we use for local shares on the computer in the Value data box and click Ok.
7. Finally, exit the Registry Editor and restart the computer.

How to disable the Authentication Loopback Check

1. First, navigate to Start > Run, enter regedit, and click Ok
2. Then, locate and select the following registry subkey:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
3. Next, right-click Lsa and point to New. Then click DWORD value.
