I just recently built this rig and have installed most of the software. In reviewing the event viewer log I found it contains dozens of copies of this entry flagged as errors:

The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
{BC866CF2-5486-41F7-B46B-9AA49CF3EBB1}
to the user NT AUTHORITY\LOCAL SERVICE SID (S-1-5-19). This security permission can be modified using the Component Services administrative tool.

Seems like something I should be worried about, but I've no clue where to start. Any help would be most appreciated.

If yours is a personal computer I would say the error is benign and just a reaction to the server in question.

Topic: Problems with SiteManager after installing Windows XP Service Pack 2

I have installed Windows XP Service Pack 2. When I now start Site Manager I receive the following error message:

In addition the event log shows the following error messages:

What is wrong?


Answer

Windows XP Service Pack 2 changes some security settings to increase security for your system. One of these increased settings interacts with the way MCMS works in a way that it prevents a COM component from being activated.

To resolve this you need to apply the following changes:

Open Component Services, drill down to My Computer, right click and select Properties.

On the COM security tab, select Edit Default... for Launch and Activation permissions

Give the Internet Guest User Account (IUSR_...) Launch and Local Activation permissions.

Sounds reasonable to me!
