Install a GPO over a VPN Link

I am checking if gpo's install over vpn? I have a msi that is set to all computer accounts over the network. We have an old Windows 2000 Radius server where the vpn accounts are created.

The VPN users connect by: logging onto machine as normal, connecting to their broadband, log on with Cisco VPN 4.6 (XP) 5.0 (Windows 7), input their assigned username and password.

I am unsure if these accounts are picking up this msi, its unknown which machines are on the vpn, just the users.

Would this simple GPO install when connected to the vpn when connected, or if not, how would I set this?

DC :2003/2008 mix

OS: Windows XP/Windows 7 Enterprise 32 bit mix

Any more questions, please let me know

Thanks in advance
