Resolution

To resolve this issue, configure the MSDTC service correctly both on the computer that is running BizTalk Server and on the computer that is running SQL Server. Open the DTC ports on your Firewall.
Configure the MSDTC service:

Open the MSDTC Security Configuration page.

1. Click Start, click Run, type dcomcnfg, and then click OK to start the Component Services management console.
2. Expand Component Services, and then expand Computers.
3. Right-click My Computer, and then click Properties.
4. Click the MSDTC tab, and then click Security Configuration to display the Security Configuration page.
To do this in Windows Vista, in Windows Server 2008, in Windows 7, and in Windows Server 2008 R2, follow these steps:
1. Click Start, click Run, type dcomcnfg, and then click OK to start the Component Services management console.
2. Expand Component Services, and then expand Computers.
3. Expand My Computer, expand Distributed Transaction Coordinator, right-click Local DTC, and then click Properties.
4. Click the Security tab to display the Security Configuration page.
