MSDTC and COM+ Configuration Tool in Vista
To access the MSDTC and COM+ configuration tool in Windows Vista, also known as Component Services MMC, you have the following options:
1. Run “dcomcnfg”
2. Or run: %SystemRoot%\System32\comexp.msc
3. Or if you prefer, you can add a shortcut to %SystemRoot%\System32\comexp.msc in Control Panel
If you have UAC on and you want to do 3, first make a shortcut for %SystemRoot%\System32\comexp.msc on your Desktop and then move it to Control Panel.
