We recently moved to a new building and have a problem with our Dell 420 boxes. We can't ghost them through multicast. We get a DHCP error when we try to connect to a multicast session. All other machines ghost without problems. We are kind of short of IPs on the floor (4 available), so our theory is that the Cisco Catalyst router has all the IPs leased, but for some reason other machines can get IPs.
These dells have built-in 3com cards that are known to have some issues with certain routers.
