| Product Name | SQL Server |
| Event ID | 15404 |

| Symbolic Name | SEC_NTGRP_ERROR |
| Message Text | Could not obtain information about Windows NT group/user 'user', error code code. |
15404 is used in authentication when an invalid principal is specified. Or, impersonation of a Windows account fails because there is no full trust relationship between the [!INCLUDEssNoVersion] service account and the domain of the Windows account.
Check that the Windows principal exists and is not misspelled.
If this error is the result of a lack of a full trust relationship between the [!INCLUDEssNoVersion] service account and the domain of the Windows account, one of the following actions can resolve the error:
-
Use an account from the same domain as the Windows user for the [!INCLUDEssNoVersion] service.
-
If [!INCLUDEssNoVersion] is using a machine account such as Network Service or Local System, the machine must be trusted by the domain containing the Windows User.
-
Use a [!INCLUDEssNoVersion] account.
