If the problem persists, please contact your domain administrator.Īn empty string means that SQL Server tried to hand off the credentials to LSASS but couldn't because of some problem. Make sure that this computer is connected to the network. This may lead to authentication problems. For example, you may receive an error message that resembles the following example: Source: NETLOGONĭescription:This computer was not able to set up a secure session with a domain controller in domain due to the following: The remote procedure call was cancelled. This error might occur if your computer isn't connected to the network. This error occurs when a user tries unsuccessfully to log in. If the clients can't communicate with the directory, the connection can't succeed. Make sure that firewalls or other network devices don't block a client from connecting to the domain controller. An incorrect DNS entry could cause numerous connectivity issues later. The accuracy of the DNS configuration on the network is important for a successful SQL Server connection. Look for any discrepancies and mismatches in the returned results. Nslookup (enter your local and remote computer name and IP address multiple times) Ping -a (use -4 and -6 for IPv4 and IPv6 specifically) If the output indicates that the account isn't trusted for delegation, work with your Active Directory administrator to enable delegation for the account.ĭiagnose and fix (DNS) name resolution issues (use the NSLookup or PowerShell example): Use the Kerberos Configuration Manager Delegation tab to check whether the SQL Service account is trusted for delegation. Use the Kerberos Configuration Manager or Setspn.exe to diagnose and fix SPN-related issues. The main reason for this condition is that the SPN is associated with the wrong account.

Note: As detailed on the Explain tab, this policy is enabled in Windows 7 and later versions by default.Īn indication of "null" could mean that the Local Security Authority Subsystem Service (LSASS) can't decrypt the security token by using the SQL Server service account credentials. Navigate to Local Security Policy > Local Policies > Security Options > Network security: Allow Local System to use computer identity for NTLM, select the Enabled option if the setting is disabled, and then select OK. Windows Local Security policy might have been configured to prevent the use of the machine account for remote authentication requests. For more information, see Troubleshooting authentication failures because of Kerberos issues to diagnose and resolve SPN issues. Use Kerberos Configuration Manager or Setspn.exe to diagnose and fix any SPN-related issues.

If no double-hop is involved, this could mean that there are Duplicate SPNs, and the client is running as LocalSystem or another machine account that gets NTLM credentials instead of Kerberos credentials. For more information, see Troubleshooting authentication failures due to Kerberos issues. Use Kerberos Configuration Manager for SQL Server to check for duplicate or misconfigured SPNs. The error could occur if the Kerberos connection is failing because of Service Principal Names (SPN) issues. There are double-hop scenarios across multiple computers. You're trying to do a double hop, but New Technology LAN Manager (NTLM) credentials are being used instead of Kerberos.įor double-hop scenarios on the same computer, add the DisableLoopbackCheck or BackConnectionHostNames registry entries. There are double-hop scenarios on the same computer. In the following table, examine each applicable potential cause, and use the appropriate resolution. There are at least four scenarios for this issue. Login failed for user NT AUTHORITY\ANONYMOUS LOGON Login failed for user '' or login failed for user '\'.Login failed for user 'NT AUTHORITY\ANONYMOUS' LOGON.Select the exact error that you're experiencing to troubleshoot the issue. The following examples are some of the common login failures. In many cases, error codes include descriptions.

This article provides troubleshooting information that you can use if you receive various "Login failed for user" error messages when you try to connect to an instance of Microsoft SQL Server. Before you start to troubleshoot issues, we recommend that you review the prerequisites and go through the general checklist for the steps to troubleshoot connectivity-related errors.
