Hi there, We have just purchased 55 HP DC7800p ultra slim desktops and I have succesfully used RIS to get a Windows XP image on them. While looking for information on this I found your problem and thought I would respond as this site has helped me many times in the past. Firstly go to the HP website and get the correct drivers for the Intel NIC for Windows XP found here. http://h20000.www2.hp.com/bizsupport/TechS...Item=ir-57735-1 Extract the files from the sp38466.exe using something like Winrar. I then simply followed the instructions found in the readme.txt in PRO1000\Win32\RIS_INF Go to the PRO100 folder and copy all the files from the Win32 folder to your image_root\$OEM$\$1\Drivers\HP_dc7800NIC directory. Go to your risndrd.sif file found in the i386\templates directory and edit it so read, [unattended] OemPreinstall = yes OemPnpDriversPath = \Drivers\HP_dc7800NIC Copy all the .sys files from the PRO1000\Win32 directory to the image_root\i386 directory but don't include the .INF files! Delete (or better still backup) the following files if found in the i386 directory, E1000325.PNF E1E5132.PNF Extract the INF files from the PRO1000\Win32\RIS_INF\E1000325 and PRO1000\Win32\RIS_INF\E1E5132 and copy them to the i386 directory. Restart the RIS service and away you go. Like I said before it worked for me so I hope this helps others. Si
