Configuring the MS DTC Client Utility

Important Windows 95 users must install the Microsoft Remote Registry Service (REGSERV.EXE and related files) before configuring the MS DTC client utility.

    To install this service

1. Double click the Network icon in Control Panel.
2. Click the Add button in the Network dialog box.
3. Select Service in the Select Network Component Type dialog box.
4. Click the Add button.
5. Click the Have Disk button in the Select Network Service dialog box.
6. Insert the SQL Server setup CD into your CD ROM drive.
7. Click the Browse button in the Install From Disk dialog box.
8. Select your CD ROM drive in the Open dialog box.
9. Select the \i386\remotreg folder in the Folders dialog box and click OK.
10. Click OK in the Install From Disk dialog box.

For more information about the Remote Registry Service, see the topic in the Windows 95 Resource Kit (WIN95RK.HLP).

After you install the MS DTC client utility on a client node, you must run the MS DTC Client Configuration program to specify a default commit coordinator. The complete MS DTC service on the computer you specify is used as the commit coordinator when:

• The application program on the client node begins an MS DTC transaction

  and

• The application program does not explicitly specify a commit coordinator.

Configure the MS DTC client utility by providing this information:

• The network computer to use as the default commit coordinator

  and

• The network protocol used to communicate with the computer you specified as the default coordinator.

  

Note The complete MS DTC service must be installed on the computer you specify as the default remote commit coordinator.

    To configure the MS DTC client computer

1. From the Main group, choose Control Panel.
2. From Control Panel, choose MS DTC.
3. From the MS DTC Client Configuration dialog box, either:
   • Type the name of the computer to use as the default coordinator in the Current Selection box.

   Or

   • Click the Select Computer button to display a list of all computers on the network. Then select the computer you want from the list.
4. Click the arrow on the Available Network Protocols box to display a list of choices. Then select the protocol used by the network computer you specified as the default coordinator.
5. Choose OK.

Note It is not necessary to run the MS DTC Client Configuration program when the following two conditions apply:

• The client application resides on the same computer as a complete MS DTC service.
• The client application does not specify a commit coordinator.

In this case, the MS DTC that is on the same computer as the client application is used as the default commit coordinator.

However, if the client application resides on the same computer as a complete MS DTC service, and the client application specifies an MS DTC on another network node as the commit coordinator, you must run the MS DTC Client Configuration program to specify the network protocol that is used by the designated MS DTC.

To do so, follow the procedure given above. You need only to specify the commit coordinator's network protocol. Because the commit coordinator is already specified by the client application, the Select Computer button on the MS Client Configuration dialog box is disabled.
