Hi, I've had RIS running successfully for the past couple of years, and rarely have any problems. But today I've received a new laptop, an Acer Aspire 3020. I'm trying to boot off the LAN so I can install XP Pro (rather than Home edition, cringe!). However when I try and boot, I press F12, the PXE environment loads, DHCP info is received, then TFTP tries to communicate with the server, after about a minute, it fails with "PXE-E32: TFTP Open Timeout". I have my old Dell Inspiron laptop, so tried booting with that, press F12, the PXE environment loads, DHCP info is received, then TFTP communicates almost instantly, it says press F12 to boot from network, if I do I can install from RIS successfully. The RIS server is a member server of our domain. RIS has been authorised in DHCP. THe RIS server, Domain Controller, and all Clients are on the same subnet, NO routers or firewalls are between the clients & server (although there are 2 switches). So I can't under stand why one client works, but another doesn't! What could be wrong with the new laptop? It's got an onboard Realtek 8110/8169 LAN card, which according to their website is PXE compliant. Any help/suggestions greatly received Kind regards Ben
