Description

The Remove-SqlFirewallRule cmdlet disables the Windows Firewall rule that allows connections to a specific instance of SQL Server.

SQL Server Cloud Adapter must be running and accessible on the computer that hosts the instance of SQL Server.

This cmdlet supports the following modes of operation:

Specify the instance Windows PowerShell path.
Specify the server object.
Specify the ServerInstance object of the target instance of SQL Server.

Note: This cmdlet ceased to work a long time ago. It's been removed in version 22 of the module.

Examples

Example 1: Disable a Windows Firewall rule that blocks connections to a SQL Server instance

PS C:\> CD SQLSERVER:\SQL\Computer\Instance
PS SQLSERVER:\SQL\Computer\Instance> Remove-SqlFirewallRule -Credential $Credential -AcceptSelfSignedCertificate

This command disables the Windows Firewall rule on the computer to block connections to the SQL Server instance on this computer. The current working directory is used to determine the server instance where the operation should occur. The self-signed certificate of the target computer is automatically accepted without prompting the user.

Example 2: Disable a Windows Firewall rule that blocks connections to all SQL Server instances

PS C:\> Get-SqlInstance -Credential $Credential -MachineName "Computer002" | Remove-SqlFirewallRule -Credential $Credential -AcceptSelfSignedCertificate

This command gets all instances of SQL Server on the computer named Computer002 and disables the Windows Firewall rules to block connections to each one of them. The self-signed certificate of the target computer is automatically accepted without prompting the user.
