Yep Exactly the same issue here.
The program we use is Net****disk (just incase I shouldn't post names)
and it looks for an IP address once it loads the network driver . Now the weird thing is that it loads it fine no errors but when it try's and grabs a IP from the DHCP server it doesn't then after a long period of time it fails -
Now there is something wrong as I do the same as Michael (update dos drivers) and before the one I currently have now (new) HP Elitebook 8470p it works fine EG.6460b 8460p etc ..... ??? HELP !! its our imaging tool we have been using since FOREVER !!
