I have the WG machine serve DHCP to all network users. Most of these users do not reboot their systems on a regular basis, but leave their systems running to get email all the time. When the lease is up, people cannot browse the internet or get email until they do a manual release/renew. I have never had this problem with a MS server providing DHCP.
What do I need to do to ensure a lease is renewed without the user being involved?
