Thanks Nicolas, the issue, is the current scanner that the client requires me 
to uses reports it.  

I would like to move them to Nessus. 

The question I keep getting  is why does one report it and Nessus does not. 
With that said, I figured I would create/find the plugin.

If anyone can add to what Nicolas has told me feel free to chime in.

Thank You in Advance --John

DCOM allows applications to be distributed across locations, the

create program ids that can have the default launch and access permissons. 

A user account is added as authentication credentials to granted permission 
to access/launch the component. When the user credentials (as a example a 
service account) are add they can recieve the default access and launch 
permissions. Alot of time they don't need the default permissions. 

DCOMCNFG is the tool that comes with Windows that allows you to configure 
the 
DCOM settings of a COM application. The application can be listed as a Name 
or 
by a program ID and its rather painful to manual check each. 


Thanks for the information. I will try to look at that later and see 
what I can do. 


Other scanners I've used will report on what user has what level of access 
and/or launch permission for a COM object. When I run an Administrative scan 
using Nessus, i've never see it report on this setting and so far i've been 
unable to find a plugin that does. 

I was thinking of writting a plugin to check the access and launch 
permission 
for COM objects. but didn't want to re-invent the wheel and thought I would 
ask 
to see if anyone else 
has. 


I really don't think you want to do that. It is easy to use the DCOM 
protocol with the Windows API but it is much more complex to do that 
with Nessus ;-)
