256986 Description of the Microsoft Windows Registry
When you remove Microsoft Internet Information Server (IIS) from Windows 2000, the default access permissions for Distributed Component Object Model (DCOM) programs may change.
This problem occurs because when you remove IIS, the
registry value is added to the Windows registry. If the value already exists, any IIS-specific permissions are removed from it, and this is the expected behavior. However, a logic problem in the removal routine causes the value to be added if it does not already exist. This registry value resets the default permissions for DCOM programs, and its unintended addition to the registry can cause unexpected DCOM problems.
