Module:

MsDtc

Tests whether two computers can participate in networked transactions.

Syntax

Test-Dtc
    [[-LocalComputerName] <String>]
    [[-RemoteComputerName] <String>]
    [[-ResourceManagerPort] <Int32>]
    [-WhatIf]
    [-Confirm]
    [<CommonParameters>]

Description

The Test-Dtc cmdlet tests whether two computers can participate in networked transactions. The cmdlet performs the following tests:

• Checks whether the required firewall rules are enabled.
• Checks whether the Microsoft Distributed Transaction Coordinator (MSDTC) network security settings are correctly configured for network transactions.
• Checks whether the two computers can ping each other.
• Checks whether a transaction can be propagated between the two computers.

To run this cmdlet, you must first enable the firewall rule for Distributed Transaction Coordinator on both computers by using the Netsh utility run the following command:

netsh advfirewall firewall set rule group="Distributed Transaction Coordinator" new enable=yes

For more information, see Netsh Command Syntax, Contexts, and Formatting.

To enable the rule using PowerShell run the following command:

Enable-NetFirewallRule -DisplayGroup "Distributed Transaction Coordinator"

Examples

Example 1: Test MSDTC on the local computer

PS C:\> Test-Dtc -LocalComputerName "$env:COMPUTERNAME" -Verbose
VERBOSE: ": Firewall rule for "RPC Endpoint Mapper" is enabled."
VERBOSE: ": Firewall rule for "DTC incoming connections" is enabled."
VERBOSE: ": Firewall rule for "DTC outgoing connections" is enabled."
VERBOSE: Contoso089: AuthenticationLevel: Mutual
VERBOSE: Contoso089: InboundTransactionsEnabled: True
VERBOSE: Contoso089: OutboundTransactionsEnabled: True
