KtmRm for Distributed Transaction Coordinator
Contents |
General Information
Thankfully, this service is no longer set to Automatic and will automatically start/stop if needed. This was not the case in Windows Vista.
Windows 8
Default Description
Coordinates transactions between the Distributed Transaction Coordinator (MSDTC) and the Kernel Transaction Manager (KTM). If it is not needed, it is recommended that this service remain stopped. If it is needed, both MSDTC and KTM will start this service automatically. If this service is disabled, any MSDTC transaction interacting with a Kernel Resource Manager will fail and any services that explicitly depend on it will fail to start.
Additional Information
None at this time.
