DCOM 10005 error

Posted on 2004-04-06
Last Modified: 2012-06-27
I am getting a DCOM 10005 error in my event log every 30m or so on my Win2K DC.  Most references I have found point to NT 4 and IIS issues.  Any suggestions?

I found this at microsoft.  

Event ID 10005 from DCOM After Installing IIS
View products that this article applies to.
This article was previously published under Q193646
After you install the Internet Information Server (IIS) service and perform a system restart, you receive the following error in the System Log of the Event Viewer:
   Event ID: 10005
   Source: DCOM
   DCOM got error. An instance of the service is already running.
This is a nonfatal error warning that the IIS service is already started but has not registered a class factory that a Distributed Component Object Model (DCOM) client requires.
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

DCOM errors will also have a long alpha-numeric string associated with them.  That string will reveal what application is having a DCOM problem.

I found several services disabled.  I reenabled and started.  This error has gone away.

Please refund points.

Noticed that 3 services were stopped on my DC at HQ.  WWW, SMTP and IIS.  Another engineer had stopped them since they didn't think we needed SMTP because we have an Exchange Server.  We are replicating to a DC across a WAN.  I read a TechNote from MS that seemed to say that AD uses SMTP for low-speed WAN link replication.  If that turns out not to be the case, I may go back and unintall the services completely.
