Win2K3 SP1 DCOM Error 10016 CLSID and MSM.AD1

I've been getting this error since installing SP1 on my windows 2003 server.


Event Type: Error
Event Source: DCOM
Event Category: None
Event ID: 10016
Date: 5/26/2005
Time: 11:09:47 PM
User: NT AUTHORITY\NETWORK SERVICE
Computer: HOUSTON
Description:
The application-specific permission settings do not grant Local Activation
permission
for the COM Server application with CLSID
{0C0A3666-30C9-11D0-8F20-00805F2CD064} to
the user NT AUTHORITY\NETWORK SERVICE SID (S-1-5-20). This security
permission can be
modified using the Component Services administrative tool.



I've read several articles in newsgroups that mention this as an issue,
however not with MDM.AD1 being the component service. I went into the
registry and searched against CLSID and came up with a couple of new
questions. What is MDM.AD1 and MDM.AD1.1?

These are the components associated with my CLSID listed above. I hit a wall
last night and could use a little help.

Correction, title is incorrect, should be MDM.AD1 not MSM.AD1

I traced this down to mdm.exe which is the membership directory manager. I
could only find articles related to site server on this, however site server
is not on this machine, Sharepoint is. IF anyone can offer guidence to
repair this issue please post or contact me directly.
