About using the virtual MMC viewer
VCS starts the MSDTC service in the cluster under the context of the virtual server. Because the MMC snap-in is not aware of such a configuration, it is not possible to view the transactions on the DTC virtual server from a node where the MSDTC resource is online. VCS provides a virtual MMC viewer, the VCS Application Manager (VAM) utility, that enables you to view the distributed transaction statistics on the DTC virtual server from a node where the MSDTC resource is online.
