DistributedCOM Event ID 10006

I recently upgraded a domain from SBS 2003 to Server 2008 R2. Every evening I get a DistributedCOM error in the system log of the Server 2008 R2 server for 2 computers (if they are on):

DCOM got error "2147944122" from the computer COMPUTERNAME when attempting to activate the server:
{8BC3F05E-D86B-11D0-A075-00C04FB68820}

I previously had errors for the XP computers until I added Allow Inbound Remote Administration Exception to my firewall GPO. I have also changed the COM permissions.

These are the only 2 Windows 7 computers that were part of the SBS 2003 domain. After upgrading the domain level, I have added numerous Windows 7 computers and they do not generate any errors.  

I do not think the errors indicate any real issues, but would like to eliminate them.

Thanks in advance.

Is it the firewall on the Windows 7 machines blocking access to them?
Try adding the inbound "Windows Remote Management" firewall exception to those two machines.  If no good, try the WMI one.

I went into 1 of the computers and opened up several remote RPC/WMI related entries - one of the WMI entries had a COM component. I'll check it soon and let you know if that solves it. Thanks for the reply.

I did not have any errors on the computer I made the change to. I will change the other one when I get a chance. Any idea why the new Win 7 computers that were not part of the SBS 2003 domain aren't having the issue even though I have not changed their local firewalls?

Thanks
