DCOM server considerations
Distributed Component Object Model (DCOM) is an extension of the Component Object Model (COM) to support objects distributed across a network.
The DCOM component is created internally using a location context of CLSCTX_ALL to permit location transparency. This component can use the location context whether it is an in-process server (a DLL) or local/remote server (an executable). This also permits the use of a DCOM component over a network.
In the case of a DCOM server, the actual component used is determined by the configuration settings made in the Windows NT DCOMCNFG utility.
