Problem
While enabling DSCP (Differentiated Services Code Point) marking for an OCS 2007 R2 environment via the following TechNet article: http://technet.microsoft.com/en-us/library/dd441192(office.13).aspx, I ran into an error when trying to save the changes I made to the ServerQoSEnabled object in the MSFT_SIPPoolConfigSetting instance.

I would immediately receive the following error:
Number: 0x80041003

Once I opened WBEMTest from an command prompt with elevated permissions, I was able to save the changes.
