When you click Retry, the same message appears. When you click Cancel, the Configuration Wizard rolls back the BizTalk Server configuration.
Note The BizTalk Server databases are located on the computer that is running SQL Server 2000.
By default, when a Distribution Transaction Coordinator (DTC) computer is not running in a Microsoft Windows domain, distributed transactions fail. This behavior occurs because the RPC security that DTC uses does not work in this environment. Therefore, distributed transactions will fail if the DTC computer is not located in a trusted domain.
By default in Microsoft Windows Server 2003, RPC security is turned on. Therefore, distributed transaction operations will fail if the computer is located in a workgroup environment or in a domain that is not a trusted domain.
If you cannot move the computer to a trusted domain, you can turn off RPC security.
Warning Verify that the computer is in an isolated environment that has a firewall before you turn off RPC security.
To turn off RPC security, use one of the following methods:
- For computers that are running Microsoft Windows Server 2003 with Service Pack 1 (SP1)
- Click Start, click Run, type Dcomcnfg.exe, and then click OK.
- Expand Component Services, expand Computers, right-click My Computer, and then click Properties.
- In the My Computer Properties dialog box, click the MSDTC tab, and then click Security Configuration.
- In the Security Configuration dialog box, click to select the Network DTC Access check box. Then, click to select No Authentication Required under Transaction Manager Communications.
- Click OK, and then click Yes to restart the MSDTC service.
- After the service has restarted, click OK.
- Click OK to close the My Computer Properties dialog box.
- For computers that are running Windows Server 2003 without SP1
