Re: Not getting a DHCP address before group policies run

The first thing that springs to mind is that you may have STP (spanning tree
protocol) configured on your switches. This is designed to prevent loops in
networks, but can introduce a delay between your NIC coming live and the NIC
getting connected to the network. This can be long enough to prevent the
machine obtaining an address via DHCP.

If you happen to have Cisco switches, the setting you want to consider
enabling is called "PortFast". See the following for some more information
about STP and PortFast.

You may also want to look at the application event log for entries from
source UserEnv, as these can be helpful in diagnosing Group Policy problems,
but my guess is that it's related to STP.

Hope this helps
