Synopsis

Retrieves the Hide Instance setting from SQL Server registry configuration

Description

Retrieves the Hide Instance setting from the Windows registry for SQL Server instances. This security setting controls whether the instance appears when clients browse the network for available SQL Server instances. When Hide Instance is enabled, the SQL Server instance will not respond to broadcast requests from SQL Server Browser service, making it invisible to network discovery tools. DBAs use this setting as a security hardening measure to reduce the attack surface by preventing unauthorized discovery of SQL Server instances. Note that this requires Windows administrative access to the target server, not SQL Server permissions.

Syntax

Get-DbaHideInstance
    [[-SqlInstance] <DbaInstanceParameter[]>]
    [[-Credential] <PSCredential>]
    [-EnableException]
    [<CommonParameters>]

 

Examples

 

Example: 1
PS C:\> Get-DbaHideInstance

Gets Hide Instance properties on the default (MSSQLSERVER) instance on localhost - requires (and checks for) RunAs admin.

Example: 2
PS C:\> Get-DbaHideInstance -SqlInstance sql01\SQL2008R2SP2

Gets Force Network Encryption for the SQL2008R2SP2 on sql01. Uses Windows Credentials to both login and view the registry.

Optional Parameters

-SqlInstance

The target SQL Server instance or instances. Defaults to localhost.

Alias
Required False
Pipeline true (ByValue)
Default Value $env:COMPUTERNAME
-Credential

Allows you to login to the computer (not sql instance) using alternative Windows credentials

Alias
Required False
Pipeline false
Default Value
-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

Alias
Required False
Pipeline false
Default Value False
