I have been directed from the Office Install/Upgrade/Activate forum to ask my question in this forum:

We have Office 2010 deployed in our 2008R2 RDS environment across 100's of servers.  We have multiple (failover) KMS servers, and there have been no issues with Office licensing.   We have noticed that Event ID: 1003  "The Software Protection service has completed licensing status check" comes up repeatedly in the APP logs on the RDS servers, presumably after the end user launches an Office application.   I understand this to be considered normal, from what I have read and researched so far. 

However, we are attempting to understand how this activity affects performance in an RDS environment, where multiple users may be launching Office applications at any given time on the server.   I have seen posts where suggestions were made to try and stop the OSPP service when inactive, but that would most likely never happen on an active RDS server with users launching Outlook and other office apps throughout the day. 

Can someone give any insight as to the need to mitigate any of this activity involved with Office KMS "licensing status checking" specifically in an RDS environment?   If we're missing any performance gains by dialing this service back, then I would like to address it.   If this behavior is by design, and in most cases benign (non-performance-impacting) then I would like to know that also.
