Troubleshooting Guide: SQL Server Error 10927

Why This Error Happens

Error 10927 typically occurs when a specified configuration value — such as a resource governor setting, memory allocation parameter, or a database/object property — falls outside the acceptable range or conflicts with an existing system constraint. This often happens due to misconfigured server-level settings, insufficient permissions to modify the target resource, or corrupted metadata in system catalog views. In Windows Server 2025 / Windows 11 environments, this can also surface after in-place upgrades where legacy configuration values are incompatible with SQL Server 2025’s updated engine defaults.

Step-by-Step Resolution Guide

Step 1: Identify the Exact Value Causing the Conflict

  • Open SQL Server Management Studio (SSMS) and reproduce the error to capture the full message, including the specific value referenced in place of %.*ls.
  • Check the SQL Server Error Log located at C:\Program Files\Microsoft SQL Server\MSSQL17.MSSQLSERVER\MSSQL\Log\ERRORLOG for additional context around the timestamp of the failure.
  • Cross-reference the value against Microsoft’s documented valid ranges for the specific command or property being set (e.g., sp_configure, ALTER RESOURCE GOVERNOR, or ALTER DATABASE).

Step 2: Validate and Correct the Configuration Value

  • Run EXEC sp_configure 'show advanced options', 1; RECONFIGURE; to expose advanced settings if the error relates to server configuration.
  • Compare current values using EXEC sp_configure; and adjust the offending parameter to a supported value using EXEC sp_configure 'parameter_name', valid_value; RECONFIGURE WITH OVERRIDE;.
  • If the error relates to a database-level object (e.g., filegroup, schema, or partition function), verify the object exists and is spelled correctly by querying sys.objects or sys.database_files.

Step 3: Check Permissions and Ownership

  • Confirm the executing account has the ALTER SETTINGS or CONTROL SERVER permission required to modify the target value.
  • In Windows Server 2025, verify the SQL Server service account has appropriate rights in Local Security Policy (secpol.msc) under User Rights Assignment.
  • Run SELECT * FROM fn_my_permissions(NULL, 'SERVER'); to confirm the current login has sufficient privilege scope.

Step 4: Repair or Rebuild Corrupted Metadata (If Applicable)

  • Run DBCC CHECKDB('YourDatabaseName') WITH NO_INFOMSGS, ALL_ERRORMSGS; to rule out system catalog corruption.
  • If corruption is found, restore from a known-good backup rather than using REPAIR_ALLOW_DATA_LOSS as a first resort.
  • Restart the SQL Server service via Services.msc or net stop MSSQLSERVER && net start MSSQLSERVER after applying fixes.

Alternative or Verification Steps

  • Re-run the original command or operation that triggered Error 10927 and confirm it completes without returning the value-related error message.
  • If the issue persists, use SQL Server Configuration Manager to reset the affected setting to its default value, then reapply your custom configuration incrementally to isolate the specific invalid parameter.
