Note The following procedure is for Windows Server 2003. It does not apply to Microsoft Windows 2000 Server.
By default, network DTC access is disabled on the Windows Server 2003 products that are mentioned in the "Applies To" section. When you do not enable network DTC access on the server, applications can only use transactions that stay on the local computer. For example, transactions cannot flow from a local computer to a database that runs on a separate computer if network DTC access is disabled.
When network DTC access is disabled, clients that try to gain access to DTC on the server may receive the following error message:
