Ok, I'm getting stuck now. Needed to add the intel pro1000 to my ris/winpe today (RIS says no without new drivers), got the latest drivers and the modified inf file, copied everything into the correct folders and made a new entry in the $oem directory, updated the sif file. Booted the first system onto ris and loaded PE, nice and painless, no problem, PE loaded. Good I thought! Better test it before I let the engineers use it and, erm, the thing will not resolve host names to IP addresses. Will not map a network drive using host name. IP mapping is fine... Checked DHCP, WINS, DNS and everyting is correct. Other systems with b57 or intel pro 100's connect and can resolve names fine but the IBM's using the pro 1000 cannot. Did notice when checking the leased IP addresses that the RIS generated computername does not show up alongside the leased address but it does with all the other networkcards (added e100, b57, yukon, realtek - all fine) If anyone can offer some help I'd be grateful... Or, does PE use a host table. Gonna try this.... Thanks. Disclaimer: I have searched the forums but nothing specific bit me in the nose so if there is a duplicate thread then sorry....
