SQLServer Automation

Automated SQL Server configuration to standardize security, performance, and operational readiness across standalone and high-availability environments.

 

This PowerShell framework provides a modular approach to applying SQL Server best practices across one or multiple servers. It is designed to automate post-installation hardening, service configuration, storage tuning, connectivity setup, and compliance-related settings in a consistent and repeatable way.

The script detects whether the target environment is standalone or high availability, then executes a controlled sequence of configuration functions against the defined SQL Server nodes. It helps DBAs and system administrators reduce manual configuration effort, avoid inconsistent server builds, and enforce a standard baseline for SQL Server deployments.

 

 

The automation covers:

  • Static SQL Server port configuration
  • SQL client alias creation
  • Firewall rule setup
  • Local administrator and drive permission assignment
  • Windows privileges for SQL service accounts
  • SQL Server service account configuration using MSA/gMSA
  • SQL Server hardening, including disabling sa, guest access, Browser service, and instance discovery
  • Password policy enforcement for SQL logins
  • Memory, MAXDOP, TempDB, and file growth optimization
  • Service startup and automatic restart configuration
  • Trace flags, auditing, error log retention, and default trace setup
  • Endpoint creation for messaging or service communication

Key Capabilities

  • Environment Detection – Identifies standalone or HA deployments and builds the server execution list automatically.
  • Security Hardening – Disables risky defaults such as sa, guest access, SQL Browser, and public access to sensitive extended procedures.
  • Service Account Standardization – Applies managed service accounts to SQL Server Engine and Agent services.
  • Performance Tuning – Configures SQL memory limits, MAXDOP, cost threshold, TempDB files, and file growth.
  • Operational Resilience – Sets SQL services to automatic startup and configures recovery actions after failure.
  • Network Readiness – Applies static ports, firewall rules, SQL aliases, and instance visibility controls.
  • Compliance Support – Enables audit-related settings such as login auditing, error log retention, password policy enforcement, and trace configuration.

Functions

  • Get-EnvironmentType – Detects standalone or HA configuration.
  • Configure-StaticPort – Sets a fixed TCP port for the SQL Server instance.
  • Configure-ServiceLogonAs – Configures SQL Engine and Agent service accounts.
  • Configure-Aliases – Creates SQL Server client aliases.
  • Configure-FirewallRules – Opens required SQL Server ports.
  • Configure-LocalAdministrator – Grants local admin permissions to defined accounts.
  • Configure-DrivePermissions – Applies drive-level permissions for SQL service accounts.
  • Configure-WindowsPrivileges – Grants SQL-related Windows privileges.
  • Configure-SaDisable – Renames and disables the default sa login.
  • Configure-GuestDisable – Revokes guest access from user databases.
  • Configure-AdvancedOptions – Applies advanced SQL Server configuration settings.
  • Configure-NTLocalSystem – Grants required sysadmin access to system/service accounts.
  • Configure-ServiceStartupType – Sets SQL services to automatic startup.
  • Configure-ServiceAutoRestart – Enables service recovery after failures.
  • Configure-SqlBrowserService – Stops and disables SQL Browser.
  • Configure-MemoryLimits – Sets SQL Server memory limits.
  • Configure-MaxDopParallelism – Tunes MAXDOP and cost threshold.
  • Configure-DefaultDirectories – Sets default data, log, and backup directories.
  • Configure-AutoGrowth – Standardizes database file growth settings.
  • Configure-TraceFlags – Enables recommended SQL Server trace flags.
  • Configure-Endpoint – Creates SQL Server endpoint configuration.
  • Configure-TraceAudit – Enables audit and trace-related settings.
  • Configure-HideInstance – Hides the SQL Server instance from network discovery.
  • Configure-SqlLoginPolicy – Enforces password policy on SQL logins.
  • Configure-TempDb – Optimizes TempDB layout and growth settings.
