Error While importing node XXXX Details: Network access for Distributed Transaction Manager (MSDTC) has been disabled

Updated June 23rd, 2017

Overview

When importing nodes, the following error occurs:

Error While importing node XXXX Details: Network access for Distributed Transaction Manager (MSDTC) has been disabled.

Environment

All NPM versions

Cause 

The issue is caused by a security restriction from the MSDTC service protocols between the SQL server and the Orion server. This setting could possibly be changed during a routine network security audit.

Resolution

The following steps can only fix the issue with importing nodes. If there are further errors with Orion Core services, run the Configuration wizard for more troubleshooting.

Check the following on both the SQL and Orion server:

Windows Server 2008-2016

 

  1. From Start, search for dcomcnfg and press Enter on your keyboard.

  2. Expand the nodes in the Console pane to locate the DTC (e.g. Local DTC).

  3. Right-click the DTC then click Properties.

  4. Click the Security tab.

  5. Under Security Settings, select the Network DTC Access

  6. Under Transaction Manager Communication, select the Allow Inbound and Allow Outbound checkboxes.

  7. Under Transaction Manager Communication, click the No Authentication Required radio button.

  8. Select the Enable XA Transactions checkbox.

  9. Click OK.

Note: It’s recommended that you review your Windows Firewall exceptions to avoid any DTC issues.  Though system and security settings will vary, you can investigate the appropriate exceptions by going to Control Panel > Windows Firewall > Allow apps to communicate through Windows Firewall and to review the exceptions for Distributed Transaction Coordinator.
