We are using Group Policy Preferences to push screensaver files to our workstations. The file is 50+ Mb.
If we set the file to "Replace" then we don't have any functional issues, but performance wise it's just killing our network copying this file down to every workstation everytime GP updates. "Update" does not "Update" the file, it just updates the properties associated with the file so this doesn't solve our issue. The frequency needs to be more consistent then a logon script can provide.
Is there a way that we can only copy down an updated copy of our screensaver when the copy of the file on the network has changed?
