There are GUIDs assigned to the MSIs which Windows tracks (and are also in the policy), so I'm sure that's how it works.
I generally stay away from GP software distribution, though. There's no BITS involved - it's straight SMB over the wire. Thanks, Brian Desmond [email protected] w - 312.625.1438 | c - 312.731.3132 From: David Lum [mailto:[email protected]] Sent: Thursday, November 10, 2011 12:14 PM To: NT System Admin Issues Subject: Software via Group Policy & logon times If you have several SW packages deployed via group Policy - once a machine has received all these apps how does it know not to reinstall - is there a tagging via GPO or does it actually kick off the installer and it's the installers job to say "yo, you already have this". I already have McAfee going via GPO and would like to do other software but I want to make sure I don't kill logon performance. Also, does it leverage BITS so VPN over slow connections aren't killed, or how does that work?
