What is the MSDTC Server Unavailability Error?

The MSDTC (Microsoft Distributed Transaction Coordinator) is a service that coordinates transactions across multiple databases. It is often used in conjunction with SQL-Server. If the MSDTC Server is unavailable, you may encounter an error message in SQL-Server.

Quick Solutions to Fix MSDTC Server Unavailability Error

Solution 1: Check the MSDTC Service

The first thing you should do is check that the MSDTC service is running. To do this:

  1. Open the Services console (services.msc).
  2. Locate the MSDTC service.
  3. Check that the service is running.

If the service is not running, try starting it manually. If the service fails to start, you may need to restart the server.

Solution 2: Check MSDTC Security Configuration

The MSDTC security configuration may be preventing SQL-Server from accessing the MSDTC service. To check and update the configuration:

  1. Open Component Services (dcomcnfg.exe).
  2. Expand Component Services > Computers > My Computer > Distributed Transaction Coordinator.
  3. Right-click Local DTC and select Properties.
  4. Go to the Security tab.
  5. Make sure that Network DTC Access and Allow Remote Clients are both checked.
  6. Restart the MSDTC service.

Solution 3: Check Firewall Settings

Firewall settings may be blocking SQL-Server from accessing the MSDTC service. To check and update the firewall settings:

  1. Open the Windows Firewall with Advanced Security console.
  2. Go to Inbound Rules > Distributed Transaction Coordinator.
  3. Make sure that the rule is enabled.
  4. If the rule is not enabled, enable it and restart the MSDTC service.
