18 DCOM Settings with the dcomcnfg System Program

Default Permissions

Meaning

 

 

Access permissions

The default access permissions for all COM objects specify which

 

accounts are allowed to access the object; in other words, call the

 

methods and which accounts are explicitly denied access.

 

 

Launch permissions

The default launch permissions for all COM objects specify which

 

accounts have the right to create the object and which accounts are

 

explicitly denied this permission.

 

 

Configuration permissions

The default configuration permissions specify which accounts can

(Windows 2000 only)

modify the information in the registry about COM objects; in other

words can also install new objects on the computer.

 

 

 

These permissions can be set individually for each object and the default properties are then ignored.

Settings for Simple Commissioning

If you make the following settings for the user accounts “EVERYONE”, “INTERACTIVE”, “NETWORK” and “SYSTEM” both at the client and server end, you will find it simple to commission DCOM:

SAccess permissions: (Allow access)

SLaunch permissions: (Allow launch)

SConfiguration permissions: (Full control)

When working in a domain, it is adequate to enter only the user accounts “SYSTEM” and the accounts of the authorized users in the lists for access, launch, and configuration rights on the client and server.

Notice

These settings make commissioning straightforward but allow every user in the network access to the computer. If you have security problems with these settings, the permissions must be restricted to individual user accounts.
