I have a Policy Server running, I'd like to know what the Housekeeping thread is and what it does.
The Housekeeping thread checks for all the latest updates
that have occurred to the Policy Store data, and applies those changes
to synchronize the Policy Store with the XPS Store
data. It makes these checks every 5 minutes by default.
The last search time is stored inside the Housekeeping thread and
the next search for XPS modified objects will be issued with
modifyTimeStamp greater than the last search time, to find any
Note that the modifytimestamp only changes when the search request
finds modified or new items. The Housekeeping thread always uses
"LastModifiedTime" for searching. If there are no change, it
keeps using the same timestamp over an over again until it
finds something that changed in the Policy Store. Then it
updates modifytimestamp to the new value of the LastModifiedTime
