Actions when configuring the Virtual MSDTC Service
When the Virtual MSDTC Service is added, the system temporarily disables the MSDTC on the
configured nodes, which causes all inflight MS DTC transactions to be aborted. The following changes
are also made on each configured node:
• MS DTC service is set to “manual.”
• The MS DTC log is set to point to the shared location on the PSFS filesystem (the virtual data root).
• Network DTC Access is enabled.
1. Open Component Services by selecting Start > Programs > Administrative Tools.
2. Expand the Component Services folder and browse to the My Computer folder.
3. Expand the My Computer folder to see the Distributed Transaction Coordinator folder and then
the Local DTC folder.
4. Right-click Local DTC to open its properties dialog, which shows the following Security dialog.
