Windows PowerShell command on Get-command Test-ComputerSecureChannel

NAME

Test-ComputerSecureChannel

SYNOPSIS

Tests and repairs the secure channel between the local computer and its domain.

SYNTAX

Test-ComputerSecureChannel [-Confirm] [-Credential ] [-Repair] [-Server ] [-WhatIf]

[]

DESCRIPTION

The Test-ComputerSecureChannel cmdlet verifies that the channel between the local computer and its domain is

working correctly by checking the status of its trust relationships. If a connection fails, you can use the Repair

parameter to try to restore it. Test-ComputerSecureChannel returns $True if the channel is working correctly and

$False if it is not. This result lets you use the cmdlet in conditional statements in functions and scripts. To

get more detailed test results, use the Verbose parameter.

This cmdlet works much like NetDom.exe. Both NetDom and Test-ComputerSecureChannel use the NetLogon service to

perform the actions.

PARAMETERS

-Confirm []

Prompts you for confirmation before running the cmdlet. Required? false Position? named Default value False Accept pipeline input? False Accept wildcard characters? false

-Credential

Specifies a user account that has permission to perform this action. Type a user name, such as User01 or

Domain01\User01, or enter a PSCredential object, such as one that the Get-Credential cmdlet returns. By

default, the cmdlet uses the credentials of the current user. The Credential parameter is designed for use in commands that use the Repair parameter to repair the channel between the computer and the domain. Required? false Position? named Default value None Accept pipeline input? False Accept wildcard characters? false

-Repair []

Indicates that this cmdlet removes and then rebuilds the channel established by the NetLogon service. Use this parameter to try to restore a connection that has failed the test. To use this parameter, the current user must be a member of the Administrators group on the local computer. Required? false Position? named Default value False Accept pipeline input? False Accept wildcard characters? false

-Server

Specifies the domain controller to run the command. If this parameter is not specified, this cmdlet selects a default domain controller for the operation. Required? false Position? named Default value None Accept pipeline input? False Accept wildcard characters? false

-WhatIf []

Shows what would happen if the cmdlet runs. The cmdlet is not run. Required? false Position? named Default value False Accept pipeline input? False Accept wildcard characters? false This cmdlet supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, WarningAction, WarningVariable, OutBuffer, PipelineVariable, and OutVariable. For more information, see about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216).

NOTES

To run a Test-ComputerSecureChannel * command on Windows Vista and later versions of the Windows operating

system, open Windows PowerShell by using the Run as administrator option. Test-ComputerSecureChannel is

implemented by using the I_NetLogonControl2 * function, which controls various aspects of the Netlogon service.

Example 1: Test a channel between the local computer and its domain

PS C:\>Test-ComputerSecureChannel

True This command tests the channel between the local computer and the domain to which it is joined.

Example 2: Test a channel between the local computer and a domain controller

PS C:\>Test-ComputerSecureChannel -Server "DCName.fabrikam.com"

True This command specifies a preferred domain controller for the test.

Example 3: Reset the channel between the local computer and its domain

PS C:\>Test-ComputerSecureChannel -Repair

True This command resets the channel between the local computer and its domain.

Example 4: Display detailed information about the test

PS C:\>Test-ComputerSecureChannel -verbose

VERBOSE: Performing operation "Test-ComputerSecureChannel" on Target "SERVER01".

True VERBOSE: "The secure channel between 'SERVER01' and 'net.fabrikam.com' is alive and working correctly." This command uses the Verbose common parameter to request detailed messages about the operation. For more information about Verbose , see about_CommonParameters.

Example 5: Test a connection before you run a script

PS C:\>Set-Alias tcsc Test-ComputerSecureChannel

if (!(tcsc))

{Write-Host "Connection failed. Reconnect and retry."}

else { &(.\Get-Servers.ps1) }

This example shows how to use Test-ComputerSecureChannel to test a connection before you run a script that

requires the connection.

The first command uses the Set-Alias cmdlet to create an alias for the cmdlet name. This saves space and prevents

typing errors.

The If statement checks the value that Test-ComputerSecureChannel returns before it runs a script.
