Just want to ask, I've noticed that under modify collection settings, under advanced tab, there are options to "Enable collection specific policy polling interval". If i check this setting, it will overide the site wide policy setting right? My side wide policy settings is set to occur every 60 minutes, which is the default. Just want to have you guys opinion, if i set the collection policy polling interval setting under the modify collection settings to a collection which is not more that 100 computers to occur every 10 minutes, is it ok or will it burden my primary server? Reason asking is because i am doing an inplace upgrade and have advertised to all of my effected users. I would not want them to wait for 1 hour just to wait for the advertisement to appear and would not want to ask each and everyone of them to everytime run the machine policy retreival in their machine client agent options in order to get the advertisement faster....
